Gamer's Gate is doing a "build a bundle"
Pick (up to) 3 games for 3€, 6 games for €6 or 9 games for €8

These are not the most high profile games out there, but Demise, Telepath, Girl With a Heart Of and Tiny & Big are all supposed to be pretty good. Don't know much about the others, apart from Sentinel 3, which I did not like.
