David Brevik, the creator of diablo is currently working on an indy game pretty much by himself called It Lurks Below. It's kind of like if terraria merged with diablo. You have to survive by growing crops and you get items by venturing lower and lower into the world using your pickaxe. It's still in pre-release on steam, but even at this stage I played it for quite a number of hours and found that it had a surprising amount of depth.

It's certainly not on the same level as diablo, but it is worth checking out if you are into those kind of games.

I really wish Blizzard would not have shut down Blizzard North and would have let Brevik continue working on his vision for diablo 3. That's life I guess though.
