Minecraft!
I'm half tempted to host some minecraft servers, since im addictingly hooked to minecraft. Some of you haven't heard about minecraft, it's a (java based) small indie sandbox game that holds a lot of promise for it in the future. Here's a video of classic:

There's so far two modes as this game is still being developed. Classic, (Free, you can create stuff etc) and "Alpha" (Zombie survival type, costs about 13 USD but worth it in my opinion.)
and basically I'm thinking about hosting possibly some "Dedicated" servers for both classic and alpha, but i want to know what you guys think.
