Where all you all coming form with this 'up against Halo" stuff from. Pretty sure halo isn't mentioned in the psp category.
And though I haven't played any of the other games on PSP I'd like to see it win...
Best story: Maybe, though as a biased KH fan who absolutely loved BBS's story I'd say it's a guarantee 8)
Most addictive: Probably not, I was hyped about this game for four-five years, though shamefully I put it down once I had 100%'d it and have barely played it since (Damn you exams), though while I was playing it I could hardly put it down.
Best Visuals: I'd say it wins this. From what I've heard it could probably top MGS and I've played the GOW entry, and though I love that series as well the visuals on it, though still amazing probably fell a little short of some of BBS's. So hopefully a win for the visuals.
Bang for your Buck: Haven't played enough of the other games to make a decision on this, but based on the fact that the disk is about to burst, being packed full of content, and that it's an all round great game I'd like to think it's a strong contender for this.
GOTY: We can hope, wouldn't that be an award for the series to take home, and maybe lure some more fans
