How would you guys feel about Vault Boy being chosen over Dragonborn if Bethesda gets a character?
Me personally? I like Fallout, but there's only one choice I have.
I think Vault Boy's biggest issue is that Fallout's themes are heavily dosed with 50's era Americana and a good helping of Nuclear War, and I don't exactly think that's popular everywhere, considering that we basically
did go there in the 40's. Not to mention I can see loads of licensing issues since the Fallout series has always been more closely linked to 40's/50's era pop songs than stuff composed for the games. Now he is a mascot of the series as a whole, and Fallout did finally pop on Nintendo with Shelter last June, but that gives him basically as much Nintendo history as Cloud had, and Vault Boy's not an icon of video gaming as a whole.
Vault Boy to me always felt like a great choice for a Mii costume though. They've had some good ones and some bad ones (Tails), but I feel like VB would just work as a Mii. I wanted Skull Kid (really, I wanted Midna or Urbosa, but I was on board with most Zelda characters) before Ultimate, but I'm perfectly happy with SK's Mii. It's perfectly proportioned and looks great in game. I think the Sans fanbase is also really happy with how that turned out (and MEGALOVANIA is amazing). Vault Boy has the right proportions to make a Mii Brawler (or give him a baseball bat or a laser pistol), so I would actually really like to see that.
