that allows you to play with all of the races in one game on TA
Sadly, this isn't possible. The maximum number of major races in a game is hardcoded.
The closest thing is replacing some of the minor races with minor versions of major races. But it isn't the same, as minor races can't win the game.
They can, however, defeat you, at least if made sufficiently powerful.
So true! Not that this ever happened to me, though!
