>>35521239>You're walking in a straight path, with new environments and locations just randomly popping up, with no actual cohesiveness.That's the single most vague description I have ever heard. It can be used to describe just about any game to date because they all do something similar.
With that said, "straight path" is the only thing there that can not be used to describe Unova given that it's one of the few games in the series to give the player more variety in exploration of routes and caves. In that regard there are only three regions that fit that description, Kanto, Sinnoh and Alola with Kanto being the exception on account of being the first game.
