I haven't played it based on the fact I wasn't interested in the gameplay style of this FF game. I'm waiting for it to be £20 used, then I'll give it a go.
Thing is, even a bad FF game is still a good game and better than most. FF13, in all it's 'press X to play' mechanics and story told to you in datalog format, was still a good game overall, with superb graphics.
I expect FF15 to be pretty good when I do play it. However, when I played that demo in March or whenever it was, I started the game collecting things and jumping around... that's what you do in a platformer. I'm not here to play a platformer. It was a bad start.
