I just still think that the point of games is to win them (in theory) and a tie means that nobody wins.
The point of games is to enjoy them and if you draw you can enjoy the result just as much as your opponent. The same can be said for supporters.
"The point of games is winning" was a bad choice of words earlier. It's true that the point of playing games is having fun (at least for most people). What I meant was really "playing a game [in which winning is the goal] = trying to win" (this also means that the point of trying to win is not winning, it's having fun).
I enjoy playing a game, not the result. I couldn't care less if I won or lost after the game is over, because it's just a game and now we're back in real life. A tie is not bad when it happens, but if a tie is likely to happen, it's more difficult to win and that, in my opinion, makes playing the game less interesting because winning is already pretty difficult - on average, you have to retry exactly once in two-player games if there are no ties, and retrying exactly once is probably close to the optimal difficulty level for maximum interestingness for my tastes. In Dominion, a tie happens probably once every 50 or so games, and that's not too often, but in Tic Tac Toe, a tie happens basically every time and it's probably the most boring game ever.
