I wouldn’t say that 360 is the smallest community. It could be that they just consolidated into fewer clans.
I feel like there are only 10-15 regulars (people who play almost every day) these days on PC. And maybe 15-20 regulars on PS3. Judging from the Bethesda forums, 360 should have at least that many.
We already knew that the community was pretty small. But after the holiday ladder started, there were several matches each day, until the two server outages. Then people got frustrated and stopped challenging.
Also, clans figured out that if they just didn’t show up to a match that there was no penalty. (Neither team gets a win or loss.) So I think that made it so people put less effort into trying to make a match they agreed to. There was one clan on PS3 who accepted lots of challenges, but only showed up to 1/5 of them… and that probably made the other clans frustrated. (Its a good idea not to give people wins for no-show matches… but there could be an attendance record or something.)
Oh yea, there were multiple instances where two clans showed up for the match, but the invite didn’t work…and neither team got a win or loss.
Brink was probably doomed on PC from the start, but if you had 1) custom match browser, and 2) clan system from day 1 on consoles, then I think that 360 and PS3 would have had very active communities, considering their install base, and how well the game suits their platforms. This game is perfect for console clans…it just needed the right framework to support that.
