yeah its hard to get a site succesful, mine managed it cause we offered soemthign different, though it was never intended to be what it is now, I just liked vbulletin and had it as a forum for my own use, and a few others, now we have over 3000 members a year on, deleted over 1000 inactive accounts.

But arcades and such wont get you users, as people can play game anywhere on the net, its only when people can compete with others, they really wanna use yer arcade.

as mholtum said, advertise, but dont take the mick on other sites, get in on another site 1st, dont just start spamming or people will never go to yer site

[edit] Also I would reduce the amount of forums you have, as its not nice to see lots of empty ones.

I started off with only 3 forums, and then added more and more as they were needed
