similar in most areas, but we'd get a few more cool people and few less cool people.
maybe a few new boards, especially in help for steam problems
off-topic would become one hell of a place, that's for sure.
community projects i would think would improve, as well as creativity.
add-ons, although i don't go there often, would most likely get a bit more traffic
and directly after blockland's release on steam and for the next few weeks, i have a feeling the mods will be on a lot more often.
