they did a ton of that stuff- wolverine and gambit's lack of smoking (both chain smokers), and wolverine's lack of heavy drinking (more than they showed in the show, a pass time of logan's is getting buzzed and bar fighting)
- lasers being fired from handguns and not bullets. tanks shared the same issue. the dc cartoons do that also.
- storm and callisto's knife fight. iirc they used lightsabers, how the phuck did street bums get those?
- total avoidance of the reverend william stryker and cameron hodge arcs due to obvious parallels of racism/fascism
etc
Actually Batman TAS was specifically set in a Noir type setting so as to sidestep the "no real guns, lazahs!" tripe that 90s cartoons adhered to.
The Justice League and JLU series also weren't afraid to use real guns.
