Upon reading on ARena Space website, I notice that they mention the ideal cost per customer. It said that in order for the customer to experience their service, the customer should consume $15-25 in estimated. It is around Php750 - Php1250. So if it is true, I think only few people are able to avail it because it is quite costly.
Only few people are ready to spend and pay Php750 - Php1250 just to experience their technology . So I think in my opinion having arena space in the Philippines is still not feasible .
