Tic-Tac-Toe from scratch in 25 minutes using Unity3d.
I have have posted a tutorial on making Tic Tac Toe in Unity and it is available on this tutorial page complete with all assets (code, art, audio). It does assume a little familiarity with Unity and programming knowledge but is still a beginner tutorial.
Hoping to do a new game next and then rework the site a little. Have fun making and playing games!
