this is a half ggame half infobow for forum game makers... the moderators probbly wont like this but it is worth a shot...
for every topic you post you get 50 points... for every comment you post you get 25 points ( on a pervious topic) and every game made inspired by the convostation here you get 100 points...
well I like forum games based on creating your own civilization. The game starts in the space stage however your stranded and you need to make a town/village by making mines and defenses. It has a tech tree allowing you to have better technology also the game has to have a few races that are controlled by the admin but much less powerful.
I think there is already a thread with something about game ideas, though I personally believe that if you can't think up something yourself, you probably shouldn't be making new threads anyway.
The whole "Get points for making topics/conversation" is generally a bad base for games.
