How do you feel about Easter Eggs in video games? For me personally, they are sort of a wild card. An Easter Egg that is successfully pulled off can make me enjoy a game significantly more, but a badly implemented one can ruin the entire experience for me. A good Easter Egg for me is:
Relevant/appropriate to the game/series/developer. Subtle. Possible to be missed. Not a meme.
The "relevant/appropriate" qualifier is the one that varies the most from game to game. A game about Batman, for example, should contain tons of references to Batman characters, gadgets, locations, and lore in the game. A game like Skyrim should not have any references to Batman at all. I also enjoy when games reference previous games in the series or other series developed by the same developers.
