From the discussion that we had on 3/19/16, newbielink:http://store.steampowered.com/app/252870/store.steampowered.com/app/105600/ [nonactive], seems to be the most appealing choice.
It's like Minecraft, but 2D. The community with Terraria is large, but nowhere near the size of Minecraft.
As you can see from the steam page, the tacky look of minecraft is not present in this game. it's just sprites (as far as my knowledge goes). It has the ability to be social, we can build a big place to hang out, yet competitive with PVP.
I don't mind forking over $10 to play with you guys. I got a friend or two that own that game anyway. What do you guys think?
