Common question.....but I will try to answer ...... Most developers (myself and posse included) are better at developing the game. Be it using Unity or something else. We are not good at the backend side of things......and know that creating our own backend will be expensive ..... so I think we will go with a service provider once we are done developing the game. Who do we go with is unknown at this point - byond.com comes to mind but not sure if they will just provide the leadeboard functionaloty or make it real deal multiplayer coz that's the real deal...My 2 cents but others may know better. me a noob.
