If the main creators of O&C and STS joined together to make an open world mmorog it would be the most epic mmo for mobile. Granted if they actually take there time with it and not release it until lvl cap is at least 50.
When u rush a game people get bored quickly and somtimes dont return. Make sure theres at least a months worth of game play before releasing. Would also give them more time to creat new content while people are still interested.

Imo
Sts has great games, servers, customer support but so little content on releases gets boring fast.
O&C amazing game lots of things to do never get bored but there servers are horrible along with there customer service.
