Kono Subarashii Sekai ni Shukufuku wo!, Isekai Maou to Shoukan Shoujo no Dorei Majutsu Recommendations
Both set where the MC is eventually ported into another world though by different means, where one is more of a spoof of MMO game based anime's their comedy is quite similar and if you liked how not to summon a demon lord you would like Konosuba. Both have fan service if you're into that and both MC's were shut ins and the shows overall has the same kind of feel but with Demon lord being a little more serious than Konosuba
Can't get enough of ecchi isekai? "Isekai Maou to Shoukan Shoujo no Dorei Majutsu" is a shittier version of "Kono Subarashii Sekai ni Shukufuku wo!" + "Overlord" : A demon lord with a harem!
Both animes focus on a shut-in gamer boy thrown into a new world full of girls. These stories have a strong comedy element with serious themes underneath.
