You figure out the pay wall pretty quick and it is nasty. You earn new heroes but if you want to add them to you roster you need to get gold coins (which are very hard to get) on top of that, if you dont recruit your heroes after 14 days, you will loose them so it will keep you playing to get the coins so you can add them to your roster. Very sneaky and it works. Youve been warned.
