I recently became aware of an open-source implementation of Bioware's Infinity Engine called GemRB. My favourite part is that it supports pretty much all platforms, including Android!
But here's the trouble: I've got a Samsung Galaxy S, meaning I don't have a physical keyboard, just touch controls. It's nearly impossible to issue a right-click command (the force-pressing or 2 finger gestures are mostly unreliable).
Is it possible to play Planescape Torment without ever right-clicking?
