Lots of potential here. In the current form, it isn't a difficult game, but I like the concept. If you tweaked some things it could be excellent. The walls and floors need to cost money. The space is a bit of an issue, why does an arcade take 4 spaces when placed horizontally, but only 3 when placed vertically? Some things like that could theoretically be a part of strategy, but there aren't enough game options. There needs to be like 20 or so at least arcades, and there is no indication that people get bored playing the same things over and over. Also, I'm not sure what role the decorations play.
