Both take place in the US in the 20's/30's. They are animated similarly, have similar music, and could later be comparable in other ways.
Both of them deals with mafia and share the same setting (America circa 20s-30s).
Set in the same sort or place at the same sort of time, with a similar art style and similarly large cast. Two very fast paced trigger-happy shows with winding storylines full of intrigue.
Baccano is more light hearted and has more of a fantasy element whereas 91 Days is grittier and more rooted in reality.
Both of them take place during the Prohibition Era.
These gangster series are both set during the prohibition era and hearken back to classic Hollywood films. They also utilize relatively subdued artstyles.
Same setting: United States, Prohibition area. While Baccano! has a more unique way to tell a story and fantasy elements, 91 Days manages to be just as entertaining with a more straightforward plot and an actual ending. Also with mafia characters, blood and violence, 91 Days is perfect if you want to fill the void left by Baccano! It did for me, at least.
Both have a 1920's setting; with both looking at the themes of the Mafia and the illegal underworld.
The use of knife fights within both series also makes both very gripping.
If you like mafia themed anime than this is a good one to get into.
91 Days and Baccano are both set in the American 1920/30s, with similar animation styles. Both revolve heavily around mafia v. mafia and involve both knife and gun fights.
The main differences and that Baccano has more of a fantasy element and also can be a bit lighter (because of its comedic characters). Seeming to the contrary, Baccano is also a bit more graphic violence wise.
But overall, very similar atmosphere in both shows.
Both have similar settings, mafia related stories and set in the US in the same era. Although 91 days don't have supernatural themes.
both are action types set in a western frame
If you're looking for a really amazing mafia anime then look no further! Both include similar themes whilst being very different in many ways but both can keep you on the edge of your seat with the amazing story and tension.
The time periods of 91 Days and Baccano! are in the prohibition era of America, with a rich historical feel to them. Baccano! and 91 Days have the main characters of the show apart of mafias. However, 91 Days is a bit more serious and dark-toned compared to Baccano!'s friendship mystery. Nonetheless, these animes are both highly enjoyable to watch.
Very similar aesthetic and setting, although 91 Days is a bit more grounded in reality.
It is quite similar to Baccano in many ways. I'll keep this short: same type of storytelling, same atmosphere, this anime awakens the same feeling of anticipation as Baccano does, very tense, dark and interesting plot, setting of the story is in Prohibition-era in USA, mafia clans and wars included. It also looks like it will be brutal and it will involve a lot of vengance and character interweaving. 10/10 so far.
Both are extremely violent, dark, take place in the 20s, involve crime mobs. Baccano! has an ensemble cast while 91 Days follows one young man, but they have a similar feel.
Similar time period, gangsters, etc.
Both series are about Mafia and settled in USA, during a similiar period time. Killings, great skills... Both series are a must watch.
