Yeah, of course! I have no problem with just one. I Just suggest it to everyone. There are plenty of people that only have one, as it can make your character more important. I know a few people that make so many characters, that each one is a clone of the other, but with X hair, and X name. If you start with one, you can always make more later! Most of the time they'll sneak up on you as an NPC, then your'll take over and start running with it! Those are the best characters. NPCs.
