A friend of mine has been working on a 2D MMORPG for quite some time that is in the style of Tibia and Ultima Online. It's been around for years now and is quite mature. There are ~120 players online at any time, but we'd like to get the number higher than this. We're thinking of new ways to market the game and I thought to ask HN. Any ideas?
You can find the game at http://www.zezeniaonline.com/.
EDIT: Further, I'd assumed it's a JavaScript game, but you support my platform, so it's not as offputting to discover my error as it would otherwise have been.
