If anyone plays, or decides to play either of these online "survival" games, let me know - I already play both of them quite a bit. Both games are in true alpha test states, meaning they're not close to fully developed and prone to bugginess, but they're already quite good. You can find them on Steam (they're "Early Access" games) for $30 and $20, respectively.
FYI - I'll probably be streaming both of these games on Twitch.tv in the near future. When I do, I'll post my Twitch profile here so, at the very least, you can check out the uploaded broadcast and see what the games are like.
