MMOs similar to Lineage 2

Games on this list were picked by feel, not just genre label — the same reasons a Lineage II player would actually enjoy them. The core criteria: PvP as the main draw rather than a side mode, grinding that's meant to be a long-term investment rather than a chore to skip, and guilds or clans that matter mechanically — not just socially — because real power in the game depends on group coordination rather than solo skill.
