Knowing your game tastes, I think it's very likely you'll really enjoy it. Always a chance you won't, but this is the kind of game Square Enix should have been making post FFX instead of steering in the direction of XIII, XV, etc.
It's very different than W3, ME or FFX, but it feels like a AAA RPG developers Magnum Opus and not the first title of a AA or Indie dev. It's nuts. It's not the kind of game I'll play through time after time like Skyrim, ME or Chrono Trigger, but it's a game that'll leave an impact I'll never forget. If I had to compare it to a movie... maybe Lawrence of Arabia (or the Godfather for others)? It's not something I'll sit through and watch again anytime soon, but the first time I watched it I thought "Wow, I get the hype. That was a masterpiece"
