Please keep things positive. Best advise I believe is to try out different sites. Find what works well for you. If you don't like it, don't go back and try another site. Nothing says you only have to play on 1 site. At one time, I played on about 6 different turn-based game sites.

With the conversation over the last month or so about other gaming sites, I thought I would add one that I don't see anyone mentioning yet. I play on another site that is entirely different than turn based individual games. It is a game that involves politics, building cities (in the sense of seeing how many cities you have and what you in them), building and establishing your military, little battles to all out war, positioning your political stance with other nations, building alliances, establishing commerce / trading, etc.
I have found it very fun over the last few months and thought maybe a few of you may have interest in it as well.
