Twin Stick Games. Not a good experience

Ok had this for almost a month now after replacing my HD7 & attempted to play GunBros & Zombie (on teh phone).

Well all I can say they are unplayable. i'm guessing it's due to the size of the screen being alot smaller.

Anyone else tried playin any Twin Sick games on Lumia 620?

Can you be more explicit? Unplayable how? It's nothing to do with touch misbehaving is it, ie being a bit sketchy? If so, this thread might be worth a read: http://forums.windowscentral.com/nok...-new-post.html
