Yumekui Merry
Log Horizon
Overlord 1,2,3
Knight's & Magic
Girls und Panzer
Fruits Basket (its a very old manga that also has an anime and is surprisingly good but last time I watched it was in 2011)
SAO: GGO Alternative
Isekai wa Smartphone to Tomo Ni
Any other Isekai series
There's still more but these are the one's that are the best for me.
Almost forgot about the .hack series of animes and movies.
