Thouch gaming and desktop games

Tap is like a left click, right? So obviously there is no right click solution. So my question is: Is it realistic to expect a solution that would enable me to play older games, like civilization 4, using a touchscreen? Intel IB and especially haswell hybrid tablets are a perfect compromise for ME in terms of battery/power/size, and being able to play civ4 or dawn of war 2 on a touchscreen while lying in bed is a sort of a fantasy I have. Yay, or nay?
