The game seems rather neat, though having at least 50% to 65% paywalled kills the "assist" functions. I doubt this type of micro-transactions was in the mobile version of Plague Inc. but still... HALF of the game is walled off by an micro-transaction that could be unfair from a certain point of view. Edit: Don't take this the wrong way Ndemic, I do enjoy playing my Steam copy of Plague Inc, it's just that some free to play games shouldn't be pay walled up to 50% at least.
