From: GeneralCortez | #001 people complain about there being old pokemon everywhere in GSC
No they don't.
Oh yes I do. Psyduck, Magikarp, Geodude, and even Zubat(who I like) piss me off. I especially hated it in GSC because most of the Gen 2 pokemon were mediocre back then and so you had to end up using a lot of Gen 1 pokemon anyway.
I also hate when a lot of the new mons get pushed back to the post game instead of the returning ones. Where The F*** is my Houndoom dammit!!!
