I've played the Penumbra Demo. Although it was a bit interesting, I didn't buy it because of the control scheme, but I may change my mind due to the bundled pricing... not a bad deal, even if I can't stand the controls.
I also have the Amnesia demo, but I haven't had a chance to install it yet. Although people say it's a good game, if the control scheme sucks again... then I don't know what I'll do.
I really want to support Indie Devs... it seems to be our last bastion for non-consolized crap. But Damn... learn how to make an interface that is worth a shit, PLEASE!
It seems like Indies and Europeans can't make a UI to save their lives! (Euro titles being things like Aquanox, Arx, Gothic Series, etc. etc. - All have shit controls - Arx being the least messed up)
Get your games from GOG DAMMIT!
