terraria had at around 6 saves what about making this one have as many as you want ... and also can be downloaded via steam cloud?
It wasn't too hard to get more saves with Terraria. All you had to do was move a save file out of the folder and replace it when you wanted to play on it again. However, I think (let me stress that: I think) the Devs have said that this won't be an issue. Just to make sure you got that: I think the above is true.
