My Gaming Collection (Now at Google Drive!)
FF10-2 was a great game, far better than FF10 in my opinion. The storyline sucked, but the battle system is so good that it alone could have saved the game, but the side content and everything else was also pretty good. Previously thinking it was FF10 only, I really wasn't interested, but now that I know the PS3 version includes both games, I'll probably purchase it once it hits $20.
I do hope the games do well though, because that might make Square Enix interested in doing an HD version of FF12 Zodiac Job System, and if that happened then I'd support them by getting that one day one. Or maybe FF12 and Dragon Quest 8 as an HD Collection to try and sell to fans of both series(since FF12 came as a demo with DQ8 it sort of makes sense.)
I do think they include both games on the Vita version though instead of what's announced/rumored as each game having a separate release for Vita and both on one disc for PS3. 95% of all content on FF10-2 is what is already in FF10, so it's just duplicate data that would already be there and would just need to be reused.
