Shameless plug, but for those interested in terraria, check out starbound. I have a topic about it here:

It is by one of the creators of Terraria(Tiyuri) and is essentially Terraria2.0 in space with a sci-fi setting. It's nearing a public beta(if you pre-order). One of the neat things I saw in a live stream they did, is the fact you can freeze to death on cold planets at night.
