Mushoku Tensei: Isekai Ittara Honki Dasu, 7th Recommendations
Grand party-based adventures, across similar styled fantasy worlds, with an MC who eventually leaves a legacy. Main differences...
7th (Sevens) is more light-hearted, is NOT an Isekai novel, world feels smaller, MC uses mainly swords & skills and his harem gets absurdly large.
Mushoku Tensei is more down-to-earth, it IS an Isekai novel, world feels huge, MC uses mostly magic and the romance is a lot more mature in content.
