Was initially happy with the service but my opinion of the company changed dramatically when I was banned. Admitting to "piracy" on the forum (when asking for a new game detection scheme) is enough to get you thrown out, not just from their forum but from the service itself. No second chances, no appeals. It is clear that these people are a bunch of fascists who like to suck up to big gaming.
Better to go with Evolve. Their game detection scheme is neutral in the sense that it doesn't discriminate against any potential sources for games. It just works. No need to detect a game or beg some fascist mods to add it to a list.
