Go with the default (Orion), it fits in well with the game.
I might, but I did pick a secondary for another game where the guy wouldn't have that style of name given the setting, and I was leaning that direction. I realize that the "canon" name can lead to some jokes in the game, and it is fitting, but we'll see.
Would be interesting to know what ppl name their MC
I happened to be watching Tombstone when I was playing my first AVN where you could change the character names, so I chose Wyatt Marshall (had an ancestor with the middle name "Marshall" and I liked it). The lead female LI had a changeable name, so she was named "Josie" (again, watching Tombstone). I like that one for brunette LIs; for other LIs, my next go-to is "Leah". I have another, more personal one, particularly for redheads, but I'll keep that to myself. (No, not Ginger Bitch - it's someone I once loved, and we'll keep it at that.)
I have a couple others I might bring out for MC characters in related stories where the MCs aren't the same person, but they exist in the same universe and might interact/get spoken of.
