I personally see nothing wrong with opening games early. In fact I see a benefit to it and one that I have personally used.
Having multiple games open at a time allows players to have more choices in which games they can choose to play. For instance, while Grujah's XIII hydra game is cool and has an interesting mechanic, it wasn't really something that I was interested in participating in. However, if it was the only game available, I would have joined it to have something to play. But since Jorbles game was open instead, I joined that, because it looked like a game I was more interested in playing.
Multiple games open at a time allows players to be more selective in which games to play. If you want to play all the games, join all the games. If you don't want to play a certain game, don't play it.
Ozle, I would hope that my opening of MVI didn't cause you to to shut down your game. It appears that it did. If so I am sorry, and I hope that you will open it again as that was certainly not my intent. My intent was to allow players to have an opportunity to look at the game I am running and decide if it is something they want to play. If not enough players sign up, I'll either cancel it or modify it.
Sure it makes the que a little crowded and there is a delay in starting games, but I don't see that being a problem.
