In fact that arena space has a 6 attraction in 1 park.. are they having a plan to have another attraction or games at their park?
Probably they will expand once the ICO is finished.
Since they already established Arena Space in some countries, I think the developer will continue to develop more new attractions that is not available in other Arena.
they should have a innovations on every game they have. people now are looking for something that is unique and have a one of a kind experience..having a latest update on each gAme is ok..
