Finished the game this afternoon, clocked in at 76 hours (finished the game in 51 days, started on March 2nd). Fought the final battle at Lv 79 with Melia, Riki, and You-Know-Who. Last boss was no freaking problem, I think maybe I had one character get KO'ed, we just destroyed it.
... Yeah, who couldn't enjoy this game? The final 10 hours or so the plot got a little WTF PLOT DUMP but the surprises were nice and it the game managed not to get its head up its ass with philosophical exposition (XENOGEARS ANYONE?!). I must admit up until the final couple of areas I was starting to get bored with the story and think, "Yeah, I know where this is going!". But the game took a 180 direction without getting silly on itself. One of the few video games in general where it seems like the plot was completely thought out from start to finish. Yeah there's definitely NO WAY anyone would've guessed the direction this game was heading, even when you think you KNOW about halfway through the game. The story from start to finish was very impressive and the ending was satisfying for a game with this kind of scale and magnitude.
In the pantheon of all-time great JRPGs, I don't think anyone who has finished this game could deny its position among the all-time greats.
This game had two weak links for me:
1) the characters - unless you go out of your way and do all the heart-to-hearts there's very little character development along the course of the main story line. Again, maybe if I had done more heart-to-hearts I would feel definitely about the characters. But really none of them stand out to me at all... except maybe... Melia? Yeah, I dunno.
2) the combat - fighting enemies at or below your level was really not engaging. Unfortunately this describes about 75% of your combat in Xenoblade. The only time combat was really fun, and it really IS fun, is when you're fighting uniques above your level. This game does truly shine when you're in a good battle, and it's fun too. This game however is paced extremely well so just when you feel like "Man I've been kicking everyone's ass, I'm so badass" you'll run up against a monster that requires your full concentration in battle.
Even with that said, the combat and characters are more sophisticated than most of my favorite JRPGs. This game is 5/5 , 10/10 , 30/30 if you are a JRPG fan. It's tough to find things to nit pick about this game.
... oh and one more thing: for a game that is so open and "go at your own pace" there was literally only ONE time in the entire game that I got freaking stuck and didn't know what to do(see my post about 10 replies above). Again, super impressive for a game like this!
