Resident evil...FOUR!(The way narrator says it) Max Payne 2 Fallout 2 (at least) Serious Sam 2 Garry's mod
Some Valve releases An actual Call of Duty Would be cool... Actual console ports of anytype are welcome I'm so bored of these "fantastic" indie games in which I plainly jump and platform. Getting old
They brought out Half Life 2 and Portal for nVIDIA Shield which has a Tegra 4 processor (the portable does anyway) and they run great. So definitely some Valve titles would/should be possible. I think they would be absolutely huge on iOS.
Diablo III: Ultimate Evil Edition Civilization V Mount & Blade: Warband Torchlight II Starcraft II or unique Starcraft mobile game
Fallout 1 and 2, Morrowind, Planescape:Torment (Most likely coming), Pillars of Eternity, Wasteland 2, Knights of the Old Republic 2 (with restoration mod), Full Throttle, Day of the Tentacle, Apollo Justice, Final Fantasy VIII to XII (save for XI), Xenogears and many more. Point being that turn-based rpgs(or auto-pause ones, at least), and point and click adventures work the best on Touchscreen, in my humble opinion. I would love seeing modern games like Skyrim, Dragon Age, Alan Wake, GTA V etc on iOS at some point. While it is not likely, maybe one day... Who had guessed that we would be able to play GTA SA on a cellphone?
I would like to see more Monster Hunter ports. Maybe it's time some of the latest titles stop being nintendo exclusives. Also, Vagrant Story and the Front Mission series. And since the iOS scene somewhat loves the roguelike genre, Zettai Hero Project: Unlosing Ranger VS. Darkdeath Evilman, and Breath of Fire 5.
