Any good game for 5$?

The current Humble Bundle gives you steam keys for Botanicula, Machinarium and Samorost 2, if you pay $5. Machinarium is excellent. I'm currently playing Botanicula which is real fun, but aims a bit more for a younger audience.

If you hurry, Gemini Rue is an excellent point and click old school adventure game with a cyberpunk theme and it's only $5 for some hours in steam.

Plain sight

i know the multiplayer is dead and the game is only multiplayer, but the game is so damn fun to play with friends, get it if you love space robot ninja's :D
