Nop, I think it's an awesome idea actually. Whisp's implemented a war system (holy war/battle royal/genocide) sanctioned by the gods… I've been finishing this up and in addition to it, I would love to add a few things like this which overlay an element of strategy on top of the fighting. Granted tic-tac-toe isn't a master's challenge, but it would make it a little more intersting.
Before I add it I'd like to come up with a few other ideas like this which wouldn't be too hard to code (maybe a new "war games" system - not like a war, but more strategy, similar to arena fighting vs. all-out pk fighting). Chess does come to mind, and it's something I am going to implement in the game in the long run in some form, but it would take a lot of time. In the meanwhile we could have a few simple games like this.
