Hi, I've been toying with the idea of replacing some of GEN 2s pokemon with a handful of later generation pokemon. I'm considering this option both for story/narrative reasons and to bypass the limits on the # of pokemon in pokecrystal. My concern, however, is that replacing, for example, pidgey with wingull could introduce a lot of bugs into the game. What do. you think? Is replacing pokemon fairly straightforward or are there all kinds of complications involved, some easily missed?
