What simple multiplayer game is possible to make ? Need some idea.

I understand that it is not possible for me to try to make some big projects now. I work alone, have not too much time for it and i am not master of self motivation.

I do not plan to make game for too much people - my server now is not too powerfull. May be 10-15 peoples online at the same time.
But it is interesting for me to make some thing interesting - not some kind of shit again

Now i make it only for getting new exp. in it, but if it will be some good idea - it will be more interesting

Card game. A platformer.... ermm... A RnR game with 2 players might be interesting. Do something like you only get the view the other persons rape to discourage people losing on purpose.
