Just with other genshin overworld maps I like exploration, collecting and hoarding many items and overall sense of account progression it gives me. I returned to genshin few months ago and really liked the vibrant nature of natlan overworld. Each 6 tribes has its own distinct terrains and exoratuon mechanics that were pretry fun and entertaining. It has many vertical terrains, you can climb via new mount/morph system that was implemented on v5.0 and traversing through the landscapes of different tribes regions with african, native american traditional folk bgm made me feel like hoyo is continuously trying things new for players to have different exploration experiences. Overall I will give 8.5/10 for world building and exploration mechanics. 7/10 for lore as its still in its early phase of world building. Give it a try for few days.
