Oh, I saw a post indicating they only had 3 left - the first 3 listed here - but it's actually 6. That's disappointing. 2 of the other 3 sound like smaller projects, at least.
If you're going to use the thread to "gauge GAF's intuition," you need to define "succeed" or "hit." Those are ambiguous terms that can be spun. By "hit," do you mean a hit on the level of other major GaaS titles (e.g., Fortnite, GTA, Destiny, or whatever)? By "succeed," do you mean turn a profit? Even a small one? It's too late to define terms now, though.
My own personal guess would be 1 (maybe 2?) of the 6 will be a moderate success - by which I mean it will turn a substantial profit and be moderately popular - not minimal, but not on the level of a huge GaaS title, either.
