I have been working with a indie developer off and on for a year giving design advice and helping with the community. Out of the performance issues i've seen, gamesparks will throttle you, they will kill your cpu power usage, and generally make your game unplayable. This is something you should seriously Consider avoiding as I've seen how they treat developers on there tiers. Also, a licence for a dedicated server is around 300$ a month from the research I've done for this particular dev. This is just comming out of there standard packages. I remember also a game called the repopulation. They went with a game engine that did some similar pricings for server hosting and maintenance. The repopulation ended up getting basically seized and was a situation of a hostile take over. I'm afraid that gamesparks may do something similar to any developers that try to make games that feel there exorbant dedicated server prices are too high. Also, while they may make a simple framework, it holds your code hostage. You have to use there framework, or go out of the way to create your own. I'm trying to save you alot of potential entrapment by telling you guys, you should look for alternatives.
