Thanks.
And congrats on finishing FF XV! Is it worth purchasing?
Its gameplay (edit: battle system) is better than I have seen in a Final Fantasy game since... ever, really. Edit: it's also quite hard, especially if you haven't read a guide beforehand.
Its soundtrack is decent to good, but a bit too limited, unless you count the pieces from previous FF soundtracks (and yes, there are at least half a dozen from each previous Final Fantasy). Its side-quests are good, if limited (not in number - in variety: there's four kinds, which is still better than most: 1)Exterminate this and that monster. In Hunts, that's enough; in quests, you may need to get the item it drops; 2)Get this or that item from the 'Chests'*; 3)Go through this dungeon; 4)Pick up 3/5/10 colored toads/fireflies/whatever and bring them alive. They often overlap. Either way, the gameplay is still more varied than usual for a Final Fantasy.
It also needs a lot of hours of gameplay to even beat, let alone do the sidequests. Typically for an FF game, some sidequests and hunts are far harder than the final boss. I beat the game when I was at level 58-60, if you want to know, though I did do a lot of sidequests.
Its story is rather engaging, but gets convoluted and disjointed from a point on (don't worry; it's nowhere near Kingdom Hearts level) but the characters themselves are not all that interesting, mostly - you aren't going to relate to them the same way one might in X or VII (except maybe when watching the end-game cutscenes).
*Chests have been eliminated; what you're doing is pick them off the ground.
All in all, I'd say that it's well worth its money.
