New Game Idea - Tic-Tac-Toe

Would be cool to play tic tac toe with voting against the bot. (Don't make the bot a perfect opponent though).

Possibly have the chat segmented and playing against each other.

Something cool and fun could be in this. Let's figure it out.

No files, tests, or entry points are named. First clarify the voting rules, bot behavior, and how chat should be segmented; the work is done only when those game interactions and acceptance criteria are defined and implemented.
