while btoom is more on the gory side, they're both stuck in a game they cannot get out of unless they beat it

gantz is on the gory side as well and has alot of nudity and cuss words, but its the same thing here, they're stuck in a game and forced to play or either die or never come back to real life.

i was always trying to find an anime that is like gantz and even though btooom is less gory and less nudity, btoom is probably the closest anime to gantz, so if you like btoom, gantz should be on your list, both about people getting into games they never wanted to be in

same thing here, but instead of them not being in a game they played, in mirai nikki the game starts by a being who got bored and wanted to see it so he can be intertained.

Same aspect here, a sister liking her brother, IMO yosuga no sora had a better story and just wasn't also ecchi every time, this anime is very similar.
