If you really want to know my thoughts on it, well....
Characters feel very flat, and it tries to capture the charm of certain tropes but doesn't exactly give me all that much reason to care about them. I feel like the series fails to invest properly in the characters who'd have the most pay off, and that leaves a lot of things incredibly lacking.
The attention feels really scattered. It spends a lot of it's time focusing on the main character, but there are breaks to the POV of other characters that develop no attachment and no interest because the character lacks any charm inherent to themself. In many cases, it feels like the cuts might be entirely unnecessary.
The premise kinda sucks. It's basically a story about game genre vs. game genre. Each character is themed after a different kind of game, but again, the lack of individual charm ends up making the characters feel bland or down right weird. Their powers are, more often than not, just downright bullshit. And usually just feel like thinly veiled plot reasons to have things happen.
The sad thing is that it plays at a cool concept - using strategies from a video game to conquer the world. But it bogs itself down with this idea that every major block in the road has to be based on another kind of game, whether that be an RPG, DND, or a Hentai Game.... The main character has some interesting moments, but he's largely boring and what you would imagine as your stereotypical Isekai protag. He inspires no intrigue as a character outside his knack for strategy.
All things considered, this series is just barely escaping the category of "mid beyond belief" with some last minute saving developments, but it's far too much "Game World Isekai" for me to consider it a good series.
So yeah, it's Overlord for people who enjoy very watered down versions of Overlord. It's nothing incredibly revolutionary or intriguing, and mostly fails to capture a good story beat for the latter half of the four novels I read...
