This is the map of Sacred Contention. Please ignore the white stripe... I can't fix that lol.
I finally beat the FE8 side a few minutes ago. It took me 1 hour and 14 minutes. The premise of this hack is very good, though certain elements of the execution are... ehh... sloppy. For one thing, the FE8 side is ridiculously overpowered. How so? Let's see.
FE7 has one additional unit over FE8, but since you have both Nils and Ninian while FE8 has Tethys, they're about the same.
God units. These are units that are so pwnage it's not even fair. FE7's god units are;
Nergal, Athos (Both have an S rank in all four magics), Hector, Lyndis, Oswin, Heath, Pegasi Sisters, NINO (Fucking supports with 4 people plus almost entirely maxed stats! Best unit on the FE7 side IMO), Lucius (The only character with an S rank weapon, Aureola, but I'll get to that in a minute, Limstella (Not as godly, but with DEF and RES at 24+, not somebody to phuck with) and Dart.
Ephraim and Eirika (Both are just so ridiculous it's sad, plus Ephraims Siegmund has 1-2 range >.>), Lyon (He's tough as nails), Morva and Myrhh (They have stats off the charts), Marisa and Joshua (Joshua holds an S rank weapon), La'Rachel (Seriously, it's sad how uber she is), ALL Of the paladins are uber bitches, and Amelia is so powerful it took 6 units to kill her off, and she wasn't even on a forest/fort tile... Next is Lute who has Excalibur with +5 SPD and she drops this if you are playing FE7 and kill her, then comes Artur who ALSO wields and S rank tome, Ross is a bitch to fight (Wields ANOTHER S rank weapon), and finally, Neimi, who wields a fucking Brave bow WHAT THE FUCK she's the only person who gets one and Rebecca needs one!
Let's check the unit class lineup.
FE7; Hector, Lyn, Eliwood
FE8; Eirika and Ephraim
FE7; Guy, Karel, Karla, Lloyd (Who is arguably the best because of his support triangle with Nino Legault and Linus)
FE8; Joshua, Marisa, Carlyle, Ismaire
FE7; Raven, Harken, (Who is arguably worthless because he's slow and underpowered) and Linus (Who is arguably OP with his three supports)
FE8; Gerik and Caellach (Who is somewhat pathetic)
Assassins; (They are pretty much worthless in this hack, except Legault who supports three other units)
FE7; Matthew, Jaffar, Legault
FE8; Colm is your only Assassin, and Rennac is a rogue, but Rennac is the only unit who can steal. I think Colm stole an elixir once, so maybe assassins can steal in this hack. I'll have to check.
Paladins; This one is a biggie. FE8 paladins are vastly more powerful then FE7 paladins.
FE7; Sain, (Max STR) Kent, (Max SKL and SPD) Lowen, (No maxed stats but he has 24 DEF) Marcus, (Your best fucking paladin I'm not even kidding.) Isadora (Yeah she's worthless)
FE8; Amelia (Almost all of her stats are maxed) Kyle, Forde, Franz, Seth (All are much better than any FE7 pally), and Orson. Duessel is worthless BTW, and he's a GK.
Generals; FE7 has the upper hand here in stats, but as you'll see later, all of FE7's upper hand stats are bullified by a powerful bonus FE8 has.
FE7; Oswin of course is the best, then there's Wallace, who actually doesn't suck that bad.
FE8; Gilliam, Fado, and Vigarde. All have a shit ton of DEF and are easily killable with
NINOany magic user. However, if you don't have any available, they're a real pain to kill.
Berserkers; Naturally FE7 has better berserkers, but still here you go.
FE7; Dart and Hawkeye. I've never once been able to use Hawkeye in battle because he starts out way behind everyone else. It's a real pain.
FE8; Ross and Dozlol. Ross has a Basilikos though, so don't laugh.
Warriors; They are actually useful against those goddamn FE8 paladins, I'll say that much.
FE7; Barftree, Dorcrap, and Geitz
FE8; Garcia, Gheb, and Binks. Gheb and Binks are virtually useless, even compared to Dorcas and Barftree. That's saying a lot.
Pegasi and Wyverns; FE8 has the bonus of three Wyverns and three pegasi VS 2 and 3 in FE7.
FE7; Florina, Farina, Fiora, Vaida (She's nearly worthless), and Heath (VERY powerful!).
FE8; Vanessa, Tana, Syrene (Tana is the only good one), Cormag, Glen, and Valter. I think Valter might have the pierce attack, but I'm not certain. I haven't seen it if he does.
Bow Users; Keep in mind that on the FE7 side, Geitz is a very good Bow user, but he's not counted because he's a warrior not a sniper/Nomad Trooper/Ranger.
FE7; Rebecca, Wil, LOLouise, and Rath.
FE8; Neimi (Fucking brave bow), Innes (REINFLACHE WTF, I gave it to Neimi when I played as FE8), and Hayden. Hayden sucks lol. But he has a white gem, which is awesome.
God Magic/other users, plus regular Dark magic users; FE8 is king in this round. You'll see why.
FE7; Athos, Nergal, and Canas.
FE8; Lyon, Myrhh, Morva, and Knoll. (Don't lol at Knoll. He's the only dark magic user on the field with a Nosferatu and he's a pain to kill)
Anima Users; I'd love to say FE7 wins because of Nino... but FE8 has Lute... with an Excalibur. Yeah.
FE7; Priscilla, Pent, (Both have physic staves) Erk, Limstella (The one with the beastly DEF), Sonia, and Nino. Always keep Nino supported, and use the thunder tome, and she likely won't die for a long time.
FE8; Selena, (Very good stats, all over 20, but not over 24) Ewan, (Why the fuck isn't he a Druid? And he sucks with his Elfire BTW) Saleh (He's ass), and Lute, who wields Excalibur and gets +5 to her 24 existing speed, for a total of 29. Plus she has 30 MAG)
Light Magic users; Valkyries and Bishops only. There is not a slayer skill.
FE7; Lucius, (the only FE7 unit with a S ranked weapon/tome. And PRF weapons are not counted) Serra (Fortify staff is epic), and Renault (14 MAG = Ew)
FE8; Artur (He has the fucking Luce tome, which > Aureola. Yeah, 25 crit) Riev (He's all right but not great), Moulder (S rank in staves? Why??), Natasha (She has beastly stats but a shitty tome), and La'Rachel (Also awesome stats but a shitty tome)
Dancers and Bards;
FE7 has Nils and Ninian.
FE8 has Tethys. FE7 obviously has a better chance here because you can revive two units per battle instead of just one.
So, upon looking at the unit lineup and their Stats, FE7 seems to have an edge. But, FE8 has a few things that make it way OP.
A shit ton of S rank weapons and tomes, swappable between units as needed, while FE7 is heavy on PRF tomes and weapons, which are locked to each character.
Better god characters. Nergal is beastly, and while Athos and Nergal both wield all 4 S rank magics, it does them no good because they have no good magics to wield. (There is only one luna tome available for each side) FE8 has two dragon characters with omega godly stats, whose only weaknesses are Aureola, Luna, Forblaze, (Bows too?) the lord weapons like Armads and such, and plain old characters with an asston of attack. However, the dragons can usually OHKO any unit they attack, particularly Morva. In addition, While Lyon isn't quite up to par with Nergal... he has Gleipnir. Yeah. He also rapes Athos.
The FE8 Terrain is better than the FE7 terrain. It's easy to take your three FE8 generals and just make a wall and demolish the FE7 characters. Lyon himself is a fking wall lol. On the FE7 side however, you just have a wide open area where you can easily pick FE7 characters off if you're FE8.
In conclusion, Blazer and DH_Ninja went to a lot of trouble, and it's very enjoyable, but it's just way imbalanced. Maybe someday the community of FE7 can try redoing this hack and making it a bit more even.
I'm too lazy to update it.
