I definitely think we should present the artistic value of Tb. It's the most artistic community i've ever seen. Sure, Minecraft has skins, but this is very different.
The whole forum in general is great, with orgs for certain types of people, clans, discussions, IRC, art... You don't even have to play the game to enjoy the community, and that's what i think is the true value of Tb. It's what causes people to stay even if they're bored of the game.
Question is, if Steam would greenlight Tb, would the forum disappear?
But as ImmortalCow said, showing it off like a "hardcore" game can really push it forward.
Would be nice to see more events, and tournaments, to see who's the best player, if more tournaments would be recorded, I think it could bring much more players to the community.
And, yeah. Definitely show off some of the user created videos. And art.
