I'll leave it as simple as I can for all of those looking for a rating or summary.
I have read a LOT of isekai related manga and light novels but when it comes to Isekai/Slice of life mix ups I tend to find them really... ehhhh, however for the first time in a long time I really enjoyed the slice of life mixed in with this isekai, and I find his outlook really great.
without any spoilers heres a summary of what this story is about.
but for those that want to take the risk of finding what I write to be a spoiler for you.
(even though this is really just based off of the first 2 chapters \_/---\_/)
now you have no reason to complain.
MC comes into a new world through a game (shocker, I know) however the world he is transported to is vastly different from both his original world and the game. In the game players exploring Magic have to completely understand the way magic and mana work, creating their own UNIQUE magic spells consisting of 56(?) letters and 10 numbers, and obviously our MC is a master at spellcraft. However the world he has been transported to is vastly lacking in magical knowledge and ability, our good old MC settles down as a teacher and from what I can tell so far, he seems to be a very good one at that.
