Hello everybody I am developping a race game for Android / iOS / (maybe)Steam that will allow asynchronous challenges. This will be made through saving online many replays (not just scores) and loading opponents' replays from a online server able to run some logic for pairings. Together with this, the game will use gold ingame currency to allow users buy powerups and so on. Finally, I will need authentication through social networks and all that stuff. It's three days now that I'm exploring possible MBaaS solutions and I know that there is a lot of debate about which is the best one. I'm completely stuck, so I ask for help here! My available options right now are: - Parse.com - Kii.com - Gamesparks.com - App42 - Playfab.com + photon.com There are tons of other possible services, but everytime I explore a new one it falls apart against these 5. These are my personal pros and cons: PARSE: stability Pros: it looks the biggest, base on alexa and google search returns. It is owned by facebook, so maybe it won't shutdown in 3 months. It recently has become opensource, that is a guarantee of fast future expansions and future stability. Cons: at a first glance it lacks some features, in particular all inapp purchase for android (is it true? and is it difficult to bypass this limitation?). GAMESPARKS: elastic Pros: claims to be the biggest one, although Alexa doesn't confirm it. Allows a incredible number of services. Cons: here and there people don't talk very well of this service and of its pricing. PLAYFAB + PHOTON: Pros: a lot of users say well about this combination. Photon itself is a real winner on google search returns, if this is of any interest. Also, Playfab looks the only one to integrate with Steam. Cons: being a noob it's hard to choose from scratch two services instead of one, with doubled learning curve. KII: Pros: At a first glance KII looks less game-oriented, but they are partners of Unity and surely of other bigs, so it looks they are playing great. Cons: I don't understand if and how inapp purchase is allowed. I think not.Pricing is also not very clear appearantly. APP42: Pros: a huge number of services, included all the gaming stuff. Pretty nice free indie developer (1 millions call) Is there some one that would like to help me in this research? Which one is worth spending time, knowing the needs that my project has? Thank you very much in advance for any comment.
