It's obvious from the reviews of the game out so far (by both gamers and professional reviewers) is that this is just a very niche style of game. Some will like it if it has what they are looking for in a game but it definitely is not a game for the masses.
It's just weird to think of Final Fantasy as a Niche type of game these days. It used to be one of the most highly praised series out there. Now it just seems that it is stuck in place watching everything pass it by hoping to get one last great hurrah.
I know it is not a game for me given the fact that I put story and character development above most everything else and that definitely seems to be the weak point for FFXV.
