I've been playing Trove and really enjoying it. It's Minecraft-ish, in that it's voxel-based, but it has RPG elements that keep things moving. It's slightly grindy, but the dungeons are pretty short so it feels like progress. I'd love to see what it's like with more multiplayer stuff, though, so come play with me! It's freemium, so there's nothing stopping you. In game I'm AbrasaxOrbos.

I was bored, so I made another FTB Server, running FTB Monster. I called it Monkey Monster. Please join me: 162.244.166.21:25790
I think it's working... but I'm bad at servers. You'll have to disable Thaumic Tinkerer Kami on your client because of an item conflict.
