Thanks all. It's a dedicated Linux server with PHP5, both my current games are on it. There are still weird disconnect problems that I just can't get a handle on even in my artillery game.

It's hard to decide what to do with the scores. Since it's kinda casual, newer people will leave when they feel like it. But once your score is higher, and there are more people to play, you will start playing more serious people thru automatic match, so it should be better for players later on as they play more.

I'm trying to find as many bugs as I can before I release it to Newgrounds where there should be a lot more people to play.
