I just bought a Logitech Dual Action controller which is basicly like a Playstation 2 controller except without the rumble feature. For $20 more I could have gotten a wireless similar controller except also with a rumble function. I haven't yet opened the one I bought and I'm considering making an exchange but I have no idea how many PC games actually include a rumble feature. Does anyone know of any? If there are very few then I will just stick with what I have. Thanks!
