That too. I can't really comment on the programming related issues, but I can agree that a touchscreen and its lack of any kind of tactile feedback makes it an absolutely terrible control scheme for almost any core genre. Anything turn based could probably be functional, if a tad clunkier than a mouse and keyboard or gamepad, but anything else will be horribly broken.
In other news, I kind of want to give Planescape: Torment another shot. The writing in that game is absolutely fantastic, but somehow I've never managed to get through it. I think last time I tried, I got frustrated at the arbitrary six (I think it was) party member limit, because once I had the last couple of characters join my party, there's a chance I could miss out on parts of their story should I not have the right character in my party when I enter an area or talk to an NPC that would otherwise trigger it. I was hoping there'd be a mod to fix that, but no, the party limit is hard coded into the game. As a completionist, I find this very distressing. Triggering, even.
