I don't need to name 5, because there's only 1... ok, actually, it's 2.
I want to see Assassin's Creed II plus Assassin's Creed Brotherhood combined into one epic Italian Renaissance AC using the new engine and graphics we're seeing in Black Flag.
Obviously, throw in all the DLC content for both games, plus some additional side missions only for the new next-gen relaunch, and you've got yourself one seriously happy guy right here.
There are other franchises I want to see carried into next-gen (Batman: Arkham series, Splinter Cell, Rainbow Six), but ACII/Brotherhood is the only game I want to see actually updated on a next-gen system... and it's really not about the next-gen stuff
(though, having that insane draw distance when looking out over Florence from a view point would be SICK!) it's that the AC engine/gameplay has really improved since ACII, but ACII is still the best game in the series by far.
