Just came across this kickstarter project for a controller, which can replace the keyboard (among other uses).
It could be interesting for some regular gamers and very interesting for gamers (such as myself) who get pain and discomfort in their keyboard hand and wrist after a prolonged gaming session.
Just google [u]Grifta Gamepad kickstarter[/u]
P.S.: I am in no way affiliated with the company, just thought it could interest some of you.
and my thumb would end up with blisters due to working so hard hehe
