Eh, I was expecting FF13 to go on longer. 35 hours later, I'm done. I realize that the other 25 hours or so is spent on sidequests and whatnot, but without any aside from killing monsters (no card game, gold saucer, blitzball *ugh*, etc.), I don't think I can spend all that time just fighting over and over. I mean the battle system is cool, but I don't think it can tide me over for another two dozen hours.
I truly was expecting the story to last 60 hours. Secrets/collectibles seem rather irrelevant in the game because the items are simply random names, there are no towns and no world map to explore, and filling up the crystarium/upgrading weapons don't seem to have any point behind it because there just isn't anything else to do beyond fighting.
I dunno.. I was having a great time with the game up until beating it. Now I realize that beyond the story line, there's just not much to do. I'm used to Final Fantasies having a heck of a lot of variety in sidequests with a bunch of different things to collect. In Final Fantasy 7, I spent 80 hours in the game even though I can beat the thing in under 30 hours, because there are chocobos to breed, awesome materia to collect, gold saucer activities, secret areas, etc. All the other Final Fantasies I played had something different to do at end game. It's disappointing that there's pretty much nothing to do now in FF13 except fight.
edit: another thing about the cieth stone missions. I just felt no reason to do them because it's just a random stone telling me to kill some random monster to get some random treasure. It doesn't feel epic at all, unlike fighting something like omega weapon.
Also, the weapons all seem so insignificant coz you just get them out of random chests in random areas, and they just have random properties and random upgrades from random components.. none of them feel epic, like say, getting squall's ultimate lionheart weapon.
So I just don't feel like collecting anything in the game. Everything about the sidequests, aside from being repetitive (the fighting only thing), they also feel really really random. "Fight random monster and get random treasure for random stone dude".
