Some idea's for you guys.
It would be awesome if you have got some sort of Profile page which each person can edit individually for his own account. Im quite sure this will boost the community.
2) Highscore page
It would be awesome to have a better 'Ladder/Rank' system, this will give people a objective to play the game
3) Clans/Guilds/Teams
Some sort of Guild or Team system, giving people the ability to gather up. Within this teams things like Private Tournaments can be held with extra prizes.
4) Custom Tournaments
Give VIP people (point 5) the ability to create custom tournaments, this custom tournaments should have an certain price (money, sponsors, players, rep). Multiple people (incl non vip's) should be able to join this. This will give more meaning to the game.
5) VIP System
People who have donated should get an extra icon or something. This will make you more revenue, and give people more reason to donate. Next to that, recurring monthly subscriptions to give people a VIP status, which let them create custom tournaments etc.
6) Prices on profile page.
With a follow up on the tournaments -> Show prices on peoples profiles.
Im so full on idea's for this game, the thing im missing right now is the community aspect. Except for the forums, im feeling like im the only one playing this game vs AI, since theyre is no real interaction with other people.
