That's not all. With Tier One, when you make a game to sell, the app store takes their cut and then TGC takes theirs and you get the rest. With Tier Two The app store takes their cut and you get the rest. The thing is, with Tier Two, you have to pay for the signatures to keep the game on market. With Tier One TGC pays for it, which is why they get a cut. I honestly prefer Tier One for the simple DBPro language and not having to pay for signatures. Both are good.

Cheers.
