>AK-47/AKM getting different stats than AR platform guns. Different than StG 44. MPX being different than Sa vz. 61 Škorpion and PPSh (standard mag, as the drum mag is indeed huge). All kinds of gun attachments available. All while not being a plainly better/worse option, just different playstyles.
That's why I mentioned Ops above. Since it fits a nice middle ground of being autistic with the 1,400 or so different real gun options; but not too autistic like GURPS where you're fiddling over things like barrel length and powder charge modifying your damage. Tons of attachments/upgrades and there's no one "best" category of guns.
Plus, I know some other guy who ran a Blue Archive game with it once, another guy even did an Arknights game in it too.
