I prefer games where the protagonist is not nameable, so that I don't have to. In Western games, if the default name is too common and generic, I change it to mine. In Japanese games, I always live it as it is.
Cool that you name your guy after your favorite character. Other then something simple or easy, I would name them a name that would make sense for the character. Like I'm not going to name a guy from ancient Japan Jack. It would not fit into the story.
Yes, I wanted something a bit unique both funny and express why I play AVN's. Like Dick or Johnson something that makes hilarious sentences. In the end every MC, male or female/futa, is now called Fuckbuddy. If the game wants a last name Masters, not really proud of that one but still Fuckbuddy Masters will live up his/her name.
I'll usually go with a name of a character from one of my old stories for the MC, only changing the names of his ladies if I prefer something different from the default.
