I did it with any qb. Played plenty with randomly generated names too.
Is your son no longer interested in the game now that Archie is out? Because that is the real contention.
It doesnt matter to EA if people are less excited, as long as they still buy it. Archie is not the difference in getting the game or not. No one single player is. Heck knowing EA they will probably figure out some sort of microtransactions to bring in players at a later date. And I am sure people will figure out how to jail break the game again to get them in there too.
