I find this game a lot of fun. I have been playing for about three months now and it never seems to get old. I did have to spend a bit, maybe $50, in the beginning, but once you get a few powerful ships, your winnings in the game will make it less likely that you have to spend. There is a certain amount of skill and practice that you will develop over time which will help you advance. The only real advancement is to get more ships, and upgrade them. I haven't spent a dime in 2 months now.
