Overall, looks like you're off to a good start, and the free games could be a lot of fun (I didn't have time to play them - is there a BTC component to them at all? If not, you may want to consider that in the future - it'd drive your traffic WAY up, although I'm guessing you'd need sponsors for it).

I do have one small piece of constructive criticism, although I'm by no means an expert on community sites.  It's the coin url stuff.... like I said, I'm no expert but I can say that I personally get very annoyed by those monetized links and tend to just make note of whatever site's being advertised rather than click on them.  So I'm not sure how much you'll get from them... I'm curious as to what other people think.  It's not that I feel people are trying to screw the site owner over, it's just annoying as heck to click on the link, wait for the ad to load (if it does at all), etc.  So, seriously, maybe ask other site owners what their opinion of coin url is and whether it actually helps or hinders traffic.

That's it... great effort, and I'll be back to check it out again sometime!
