I played these games in fun mode. For the most part, all the games are identical, but just have different symbols and variation in bonus rounds. Looks like they didn't spend a lot of time on development or originality and uniqueness of each game.
This effort is probably a strategy to offer something other than the rtg brand, but they really are rtg in everything else. The same cds complaint area which does nothing and everything else associated with rtg. Payouts and slow pay will probably also be just like rtg. They're getting some revived business because it's new, but I would expect the same results as rtg (because that's who you are dealing with).
