IDK, what else do you do with rodents in a game? Set traps? Shoot with guns?

I'm guessing the devs were born in 1988 or thereabouts and wanted to set the game in their birth year or something like that. Or they picked a number that's somewhat long ago but not too long, and ~35 years ago is something I'd probably come up with (it's not a neat number like 25 and 50), it's far enough back that it's old, but recent enough to feel familiar.

Occam's razor: they're probably not Nazis or Nazi sympathizers. I had never heard of the meaning behind "88" (granted, I'm not that interested in neo-Nazi symbolism), and I was born near 1988. Maybe I'd change the name, IDK, even hearing the arguments here I really don't see an actual connection so it's really no big deal to me. Then again, I think it's a stupid name regardless, so I probably would've been more clever.
