On our Bravado Waffle Studios blog, I posted an article on why we are going to be releasing our first game RoboArena for free and how we plan on making money with it: http://www.bravadowaffle.com/2010/10/roboarena-will-be-free-to-play/ It's pretty exciting in our opinion. Check it out and let us know what you think! We are going to be making the in-game purchases and avatar upgrades very similar to how Gunbound does it. The free-to-play model is something that we see a little of in the App store, but I don't know that very many games have pulled it off successfully. Other than anything made by ngMoco which obviously has done it right, Pocket Legends certainly comes to mind when I think of a game that has successfully done this. I think Pocket Frogs might also have done it well, but I haven't seen any indication on what their profit margins are. What do you think it takes to make a successful (readrofitable) free-to-play game? Do you think there's a future for this style of game in the App store?
