It's a little bit bothersome that FE13 only has 3 files available (yes, I am well aware that other FEs had 3 as well), and I won't be getting one of those R4 dongle thingies that shadowofchaos has for extra files.
On my first run, I made a few mistakes like letting a few characters die (didn't bother resetting because I didn't care too much for them), wrong promotions, mistakes like that because I was playing "blind" and hardly knew about the game. I've beat the Paralogues and The Future Past 1, SB2 & LB2.
I kind of want to start another file so I could do the things I didn't do in my other playthrough, but there's that sentimental value for the first run that's keeping it there. I have 37 hours of play there.
