In addition to Aus Snow's excellent suggestion, I can recommend John H. Kim's awesome RPG Encyclopedia. It is absurdly huge, includes forgeign language stuff, and even describes a little about the setting and system of most games.
But, yeah, as everyone's been pointing out, there are enough systems out there now that it's almost pointless to try to list them all. There are new ones being made constantly, and there are ever-branching subspecies of each major one. It's a beautiful time to be a gamer.
So I think the question here becomes "Why do you need such a list?" Is there anything in particular you're looking for, or do you just want to get an overview of the whole hobby as it stands today?
