I think what is the real issue to disagree with with the list of the OP is that those are all multiple title IPs.... but when you think about it most of these had that much good reviews for their launch title and really became bland or bad or deteriorate with time.... but Halo 1 pretty much made FPS really viable on console.... zelda or link is one of the best console RPG we had back on NES (yeah I know about the other but did they survive) the conceptual idea behind the first bioshock was brilliant..... call of duty made the real army FPS game hot on console (arguably medal of honor too and some others) GTA created it's own genre etc etc.... so yeah the X version suck or is still more of the same.... but it is like most movies rarely equal what the first edition made for itself but just the fact that it is as good or almost as good is enough for people to ask for more because they don't get tired of it just yet.... and upgraded level design couple new things and it's enough for them to chew on until the next one..... not many games can even pretend to half of that especially after 4 ,5 ,X iterations
