Suzuki Ichirou works as an extremely overworked programmer on two different games, juggling multiply tasks. After 30 hours work he crawls under his desk to sleep and wakes up in an rpg-like world, with mixed elements from the both games he was working, looking like a high-school kid.
When he is attacked by an army far above his level, he uses three meteor showers, that eliminates everyone, turning him from Level 1 to 310, with all loot at his power.
Yes, it's like Isekai, and because of that I'll watch it for sure.
EDIT: There is actually a manga source for this one, I read 6 volumes, after which I can surely say that this is like Isekai wa... though has some freshness to it as to how a normal 30 year old guy, that looks like he is 15 would behave. I actually applaud that Bordel scene. Another applause for a part that made me remember to re-read Hulk World War.
