That's actually the best Adamantoise so far. Wasn't expecting that one. Personally I will buy XV because it's a new FF main mothership title so I say why not. What I'm purely interested in is the story, combat, and being a completionist for post-game content because I'm a hardcore fanatic to test oneself against superbosses+cameos, finding builds for characters, performing hard things and so on. We can't say that the story won't be great...I mean the game is not even out yet to truly judge it this early. I was skeptical with how the story might play out with typical directions but I like being surprised so who knows.
What I'm "really" waiting for is Dissidia, but I've also been waiting for a new FF main title too. FFXV has been in the talks for quite a number of years now (Literally since the beginning of PS3 days console release) and even had a title change, it was about time they started working on it so I've been waiting for it as well.
