I'm building a 3D tic-tac-toe game and this is what I've implemented so far:
- 3D renderer with texture mapping
- Playing against the computer
- Playing online (multiplayer)
Now I'm a little lost what I could add. Obviously, tic-tac-toe isn't that exciting or advanced, but I just miss something to salt it a little bit.
Therefore, could anyone please suggest some ideas that would be worth implementing?
