Some gamers are upset that this is only one save file per account. I’m sure this is done because of the very unique Pawn system. One pawn per account is uploaded to the pawn server. Pawns are very complicated. They learn about monsters, quests, and bring back items for us. I don’t have any issue with this. In the first Dragon’s Dogma you can change vocations and the way your character looks anytime you want–same for our pawn. The game also repeats.
And if you really really want to have more than one character, you could back up the current save file and start a new game.
If they sell a lot of copies then their size and resources will also increase, and to be honest server resources at that volume are not going to be three times as much if they have three save slots since most people will probably only use one.
Additionally, I don’t really care because in most cases they can address scaling issue with better optimization so it really is not something the customer should even care about.
