Recommendations

I've recently got into Lit RPG's but some of them are doing things that frustrate me through other genres aswell and I'm curious if you have any recommendations. I am also just looking for good recommendations similar to what I have said I read so please list any worth checking out. I need like ~50 books before I deploy.

Books I have enjoyed : - The primal hunter - A soldiers life - System Universe - Past Life Hero - Monsters and Legends

Anyways I love the character development, world building, and story these give so any like them I am interested in. What has frustrated me in some of these relationships. I never thought I would care for romance or anything, but if there is romance in the story can't they just get together already or like how System Universe does it and the character just obviously not one for relationships.
