I hate straight ports of games that were clearly designed for a gamepad or a mouse/keyboard, the big shame is that there are so many of them when there must be so many untapped touch screen game paradigms out there.
This is why I am skeptical when people say that tablets are the future of gaming , either we would have to all re-evaluate the sorts of games we want to play (no more FPS, platformer etc) or we're going to have to start plugging extra peripherals in (at which point we have just re-invented games consoles).
