add a campaign, ways to upgrade your ship/have an inventory, have items and guilds. also if someone is not moving kick them, and people should be able to join a running game if its not full. Also tournaments and prizes
I think it would be nice to have a 2v2 pvp option, and maybe a 3v3, as well as tournaments with prizes, guilds etc. more skills eventually, and pets that actually do something, as well as face items that do something as well.
