Isekai Meikyuu de Harem wo

Overall Rating 5.8 out of 10 - Deeply flawed, but with more positives over negatives experience. 

I cautiously recommend watching.

This anime is really guilty of false advertisement.

I will begin with what is bad about it.

First of all there is no real harem. Most other girls only appear in the epilogue and in the opening sequence.

Second. All video game aspects are lazily done. Monster selection is few. For the first half of the show he basically fights the same type on enemy in the identically looking corridors of the same maze.

Third is excessive details of hardships and privation of medieval life like bathing in barrels surely could have been avoided.

Fouth. I rarely complain about slow pace of any show but this one is somewhat too slow.

Good things are few.

Roxanne is rather likable girl overall. She has some flaws, but overall almost a waifu material. Though it is somewhat hard to tell if it is male MC who spoils Roxanne or she herself has some assertiveness.

Seri is better girl overall. Smaller and more girly in general.

Other harem girls do not get enough screentime to tell anything.

Lack of more significant flaws like violent tsundere girls, sub MC and other stuff I hate can be considered a positive thing as well.

Overall, it can be considered a deeply flawed, but with more positives over negatives experience.
