Final Fantasy XIII-2: Beaten. Final dungeon was good. I wasn't able to beat the 2x Schroedinger + Proto-Behemoth fight (did beat another Proto-Behemoth but I was probably a bit lucky there) though in retrospect I could have messed with paradigm formations and possibly done something good there. It's okay, it was a good warmup for the final.
Final boss was a fun fight! (gameplay spoilers follow from here) I had adopted a rather defensive set of paradigms to deal with some of the enemies in the final dungeon. This is a terrible idea against the final. Everything about that battle stresses having decent offence (although obviously you'll need some defensive strategies too since there are debuffs and it had too much HP to blitz). I dunno if you can actually see Doom like in FF13 but I still had to give up the battle once and rejig my paradigms because there was just no way I was beating the boss in a reasonable time without at least one full-offence paradigm for certain spots in the battle. Ended up going with the following (Serah/Noel/monster listing):
SAB/RAV/COM, SAB/RAV/MED, RAV/RAV/COM, RAV/COM/MED, SEN/SYN/MED, SEN/COM/MED
I didn't use the last one that much ultimately (although it did payoff as a "stabilise enemy chain while staying on one's feet/removing buffs) but everything else got serious use.
I didn't do much optional stuff (obviously), had 41 fragments I think? I finished with Serah having 3200 HP and Noel 3400, with the two monsters I used in the final battle, Flanitor (MED) and Orion (early peeker COM) having around 3500-3700. Game time was about 25 hours.
Overall, well. The game's low point is undoubtedly the ore fetch quest to advance the plot past Academia 4XX. What the hell, game. Other than that the game is a bit disappointing in a few areas. Due to non-linearity the experience of individual fights was no longer tightly balanced like it was in FF13 (right down to the star rankings), and the game suffered very inconsistent challenge as a result, which made it harder to enjoy at points. They also nerfed SYN/SAB (though this was arguably needed, it did make randoms less fun because the optimum strategy was far more often just to use a permutation of Commando and Ravager), and stripped you of a bunch of skills while adding little in return (Wound doesn't make up for no Pain/Fog/Haste/Slow/Enelement/Barelement). Pretty eh on the monster stuff... for instance, at a certain point while levelling up my Flanitor in the final dungeon its HP, which had stalled at around 1000-1100, suddenly started increasing by 150 per level, which was kinda WTF (how was I supposed to predict that would happen? Makes me wonder what other monsters I missed). And just aesthetically and narratively I guess I'd rather have people! But yeah, basically the gameplay experience isn't as good. Still pretty good because it's still FF13, it has great polish decisions and isn't afraid to kill you at points if you approach things wrong.

Plot's weird and is both like and unlike the first game. Unlike in that it gets notably better as the game goes on! Some of the stuff in the last two chapters was quite good, particularly the dream worlds. Also, the endings. Wow, great stuff. The main one is... haha. Just a delicious subversion of RPG norms. (The game tricked me into thinking everything would be sunshine and rainbows and then everything turned horrible with the deaths of Serah, Lightning, and the realisation of Caius' goals even in his defeat. The best part is THE GAME SAID ALL OF THIS WOULD HAPPEN and I sorta brushed it off with the "oh it's an RPG through sheer force of will we'll make everything turn out fine anyway!") Also Youtubed all the paradox endings and many of them are surprisingly great, some of the best I've seen in the genre, a fun series of what-ifs mixed in with the occasional one that is completely silly ("Mischievous Mog's Marvelous Plan With Flan!" is somehow more ridiculous than it sounds).
Of course, like the first game (in fact even moreso), some of the raw plot stuff shouldn't be taken too seriously (time travel's inherently a mess and I refuse to think about it, I'm sure it has plot holes everywhere but I will await Snowfire to analyse them or something). And it's, on the whole, more about the characters. Serah is quite good, as is Hope (though neither is amazingly deep). Noel's a bit of a miss... inoffensive, certainly, but a bit bland, and I thought the weakest part of the endgame plot was his showdowns with Caius (during which Serah does a lot of politely sitting there waiting for them to have their manly showdown or something). Noel does at least say things to Caius that badly need saying, so he can get some points for that. Caius, of course, is a complete tool and has an -incredibly- unsympathetic motivation by the standards of villains who aren't just out to devour the nearest baby. But the game doesn't really try to paint him as anything else, and does do a couple things that perhaps make you understand a bit more where he's coming from in the endings which is a nice touch at least.
Not sure where the game scores. I had it pencilled in as a 6 but it's one of those games helped out by the end. Final dungeon was a high point gameplaywise, but unlike, say, Blue Dragon, it can't drag up the game's gameplay that much because it's quite short. Plot doing some good things was more unexpected though. Could be a 7 after all, I'll think about it. Fun enough game, disappointing in a fairly expected way but I'm quite glad I played it, and far better than a certain previous Final Fantasy direct sequel.
Not doing the optional stuff any time soon if ever, I haven't even gotten around to that in FF13 and that sounds much more up my alley than this game's fetchquests!
