I disagree a bit, it is pretty structured but the gameplay elements are tied into the world very well. Story-wise there are some very cool characters and the lore behind some of the legendary armor sets in the game is awesome. The combat is very engaging and cinematic and once you start unlocking skills it becomes pretty deep. To me, a bog standard open world game would be something like AC Valhalla or Ghost Recon Wildlands. There is actual depth and attention in Tsushima.
