I know I'm gonna piss some folks off with this comment....but I'd really hope they choose any indie character other than a FNAF one.
The only reason FNAF even got popular was due to game theory giving it free promotion. I also hated the turn FNAF took with it's "Story", the original game was loosely inspired by a real event that happened at a chuck e cheese's in the 90s, and IMO fnaf was way creepier when it was just that. But then it decided to add so many ridiculous plot points with sequels, and everything got so bloated that it was no longer scary or even remotely creepy.
I mean, gratz to the developer and all as he realized he had a gold mine and ran with it, and did so in a really clever way that ensured he'd make bank, but damn I really wish he would have quit at the second game.
Of course also I just feel like Shantae is more deserving, so there's that too, I feel she deserves a spot before all other indies. She was the OG indie when indie developer or indie games wasn't even a real term yet.
However, like I've stated in the past, as long as Geno get's in, IDC what other game characters get in, I might not like the choice, or feel someone else is more deserving, but I'd learn to accept it. The only characters i'd NEVER support, and would actively protest, are cartoon and comic book characters like DBZ goku.
