Another example: Pokemon Ranger and Coliseum games (note that I haven't played any of the newer Coliseum games, just the first two.) They're nothing like the regular Pokemon games and they suck ass for that exact reason. Don't get me wrong though, they really don't need to make anymore Pokemon games period. Every single one is just a remake of the one before it with extra monsters and different names for people and places.
I guess I'm just pissed because I'm bored, don't want to do anymore programming today, and I have no games to play except shitty ones or ones that I've finished a million times (and 90% of them are shitty as well.)
