Honestly? You must not know the difference in power from iOS devices to PC. Half life has a small chance to work, L4D? None, it is still a recent game, with recent graphics. It's virtually impossible to run it on a iOS device with 30+ FPS.
Yeah, that would be the case if you were EMULATING IT IN SOFTWARE. He's talking about actually having the game running natively- which, with a few adjustments, would run fine! I hate how everyone underestimates emulation power. Not you, people in general. They say "PS2 can't even emulate smoothly on a high end PC" and my middle range PC runs PS2 games at 50fps. I've tried running the quake port of half life on Android. It runs smoothly! Half-Life wouldn't lag on iOS! HL2 would.
Star Ocean 2 Phantasy Star Portable 2 Final Fantasy Tactics Advance 1 & 2 because I never owned that gameboy Torchlight
Metal Gear Ac!d Metal Gear Ac!d 2 Orcs Must Die! Phantom Dust Panzer Dragoon Orta Toy Soldiers: Cold War Monday Night Combat and............any "proper" Castlevania game
Star control 2. Also known as The Ur-Quan Masters. Free to downnload on your pc. I highly reccommend it. If you've never played it and think GoF is a good game, this one will knock you on your dupa.
None of these are even games dude. But it's nice to see another Black fan who very badly wants a sequel.
