I'm more of a Kingdom Hearts guy more-so than a Final Fantasy one.
I've only ever played Final Fantasy XV, which I thoroughly enjoyed, and played a teeny bit of X. The turn based combat has kind of always kept me from exploring the other games, though I'm familiar with a lot of the lore that surrounds them.
I've wanted to play VII for awhile now, but now that they're making the remake I'm just waiting for that to come out.
Everyone complains about all the content that was left out of XV but I thought Kingsglaive was freaking rad, and I loved Advent Children as well.
