Activity is a given, but Bukkit's what I usually do but the set up varies update to update. Modpacks are foreign to me as far as hosting. Either way, I'm simpleminded enough to entertain myself with most anything. I just...need to branch out and would rather experiment where other's give a shit about playing.

I'm flexible as long as it's not dumb and we don't have the beekeeper mod. I get way too obsessed with breeding stats and making the perfect queen bee. Simpleminded.

Terraria's good too, but like you said, its hard to find a crowd for it. Even I drifted to starbound servers run off my laptop and have yet to return.
