i loved penumbra, but i lost interest in the demo. the next penumbra game (or "the real game" i might say) will push this game up my imaginary hitlist again
currently i am looking forward to
Defcon, a really great realtime strategy game (not a click-around-like-an-idiot strategy game) being shipped/release this friday,
Secret of ultimative legendary Fantasy: Unleashed (SoulFu), the "sequel" to egoboo,
Unreal Tournament 2007, for which i am going to buy a new computer since mine already gets old (at least the graphics card does. since my GF6600GT died a few days ago... i had to get back to my GF3ti200 :/)
also i currently enjoy playing
Clonk some side scrolling jump and run and fight and dig and build and mine and throw and fly and ....... game. really lots of fun, especially the newest alpha/beta/whatever it is that has a native linux client and decent network(/internet) play capabilities.
see the trailer!
also i like trying out everything that comes with a linux client (like penumbra)
