Anybody else play this? It's still in beta, but it approaches monetization a bit differently in that the only thing you absolutely need "Platinum" (the currency that costs money) for is having more slots for weapons or warframes, or buying colors or things to customize your Sentinel (pet). Everything else can be obtained through normal gameplay - and the gameplay is very fun. It has a badass space ninja feel to it, and all the levels are randomly generated through a modular system. Digital Extremes is very good at listening to player feedback, and there's no arrogance to be found in them whatsoever. They look at how beta players play the game and how they feel about it, and they continue to add new content and make changes to encourage the kind of cooperative play they want the game to have.
