So, First of all, It's a full remake, and quite different from the original game (especially combat wise), good to say this as people might find it annoying (I don't, I believe they've nailed the combat system).
The game itself is absolutely incredible, graphics are stunning, controls are intuitive and easy to learn, LIGHTING IS ABSOLUTELY INSANE.
Music is also extremely well done as it's adaptive and changes depending what you're doing, but never stops.. quite a great experience there.
Onto the cons:
Just like the first game, you'll need 3 parts to complete it, and knowing Square Enix It might take a looking time. However many hours in and I still have to finish the first part :
Not sure if it's worth buying a PS4 for it, but it's definitely worth buying the game if you already own one (I know is not your case)
It only goes up to Midgar though right? I'm a little skeptical because all the stuff I remember from the original is the stuff towards the end of the game (all the minigames). Music is a huge part for me, so hearing that is a huge plus. Thanks for the input!
Since I'm not a gamer, I'll probably gift the PS4 to my nephew.
