I like Drayano's romhacks and it's imitators for increasing difficulty without making it a grindy mess, (usually) but it always rubbed me the wrong way that they allow you to catch every single mon of that gen. It feels like it shits on the identity of the region. I can just not use the added mons, which is what I do, but the rest of the trainers still use them.

Anyway, romhack thread? Post some good ones here.
