Groupees have a new bundle which includes the quite-interesting Bionic Dues, as well as Airship Dragoon, Syberia 1&2, Steal&Steam, plus various music, ebooks, comics,
from a minimum of $1. Bionic Jews is a trading cards game, so you'll at least get back some of your dollar that way.
Gamersgate has
Pixeljunk Monsters Ultimate for $2 / £1.40. It's a Trading Cards game, and I've been testing it for touchscreen Win8 hybrids this week - it works perfectly without keyboard or mouse, EXCEPT for needing to press "Enter" before the main title screen! That one oversight means it needlessly requires a keyboard!
