Very similar in the fact that both are Isekai involving a hard core gamer being transported as the main character. Both MC's are also transported into a villainous role instead of the hero part with OP powers none the less making for a great story.

The main characters are introduced in a new world and quickly discover they're they understand the inner gears of magic... and invest their talent on a harem.

They're both isekai anime. If you like the genre, you will probably like them both. They are both mostly light-hearted shows, and the protagonists don't take themselves too seriously most of the time. The both have absurd moments that make you laugh out loud, and they both throw some unexpected things your way (tsundere dragon, how to get closer during a summoning ritual).

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

The main characters are introduced in a new fantasy world and enjoy life as they build their reputation of being the most powerful being in this world and as they rapidly build a harem.

- Main protag sent to another world - Initially misunderstood - 2 girls to follow around with MC - Game-like mechanics (RPG fantasy) - Slaves as an early driving factor (less mentioned later) One standing difference is that Diablo is very strong from the beginning while Naofumi starts off with nothing, to get stronger later throughout the series. Different personalities as well.

Harem Ecchi Comedy Demons(in a way) Issei and Diablo are similar in some ways.

The same MC whom were anti heroes who have a harem and doesn't know what to do with it and the same MC whom has demon like powers.

Overpowered demon lewds, eh, lords enter the scene and form a harem. Those are borderline hentai and you should watch them. "Shinmai Maou no Testament" is more serious, like "High School DxD", while "Isekai Maou to Shoukan Shoujo no Dorei Majutsu" is more about the comedy, just like "Kono Subarashii Sekai ni Shukufuku wo!".

Same theme than Isekai Maou(...), with a main protagonist "god-tier", and two girl who follow the hero ; the only difference is there are more ecchi in Isekai Maou... 
report Recommended by Barroblade
Both are isekai anime where the protagonist/s end up on a strange new world where they kinda fit in better than the real world. Both Over powered protagonists and both has shared themes like comedy, harem and echchi.

report Recommended by Kittycat_Neill
This is the story of a demon lord forming a harem. It's a light comedy mostly revolving around lolis and a powerful demon lord.
