I have 230,000+ users on other applications I can push to this one to see how it does. 10-20k daily traffic! Ill quickly be able to discover if it's going anywhere. My female friends think it's it's pretty awesome, and my marketing friend who is spending 80,000+ on a fantasy sports app thinks I'm going to make more than him. It honestly doesn't matter if most people even play the game, it just has to spread via the gifting part. He should have probably gotten a grant from the Facebook fund for his app, thats a bit of an investment, whatever... He can afford it! He's an affiliate marketer like I use to be.
One thing about social applications is that quality doesn't matter much... 90% of viral is in the wording of notifications and invitations. Theres also shady tactics like force invitations, hidden notifications... Etc... Hopefully I don't have to do that. I managed to boost one app from 26-40% accept rate with a wording change! I am going to be using the same invite style on this app as the one I managed to get to a 40% accept rate. If you know how to work it, you can make crap fly... lol! I have never lost $$ on an app yet. I swear apps are just like affiliate marketing with all the split testing of notifications and invites involved...
There is plenty of crap that flies, and some quality stuff too. Social apps...
http://adonomics.com/leaderboard/appsThis is just fun a side project besides my partnership with a interactive company in developing NRT games with SmartFoxServer.

Initial tests of 35,000 users on the first NRT game went decently... It's holding level. Now we just have to re-ajust the game formula and the HoRRIBLE game controls I thought up, and get non-placeholder graphics... Put in the leveling/ranking system and lobbies! And our first one should be launched next month!
