It depends on the game. If I buy a game from a smaller publisher I expect it to be a complete work with full story line. Unfortunately… When I buy from a large publisher I expect to be getting a ¾ complete game that will give me expansion packs.
This isn’t the case with Nintendo games though. I feel like and Nintendo game is just done and any extras are… Extra.
I think it might be a retroid pocket mini. Here’s a list of reviews on these little handheld guys I found in my hunt that might be helpful.
