I don't think I'll get it for the same reason I didn't pick up Street Fighter IV. It requires more practice and research to be competitive than I have the time or patience for. Not that that's a bad thing, though. I have a lot of respect for people who dedicate themselves to deep games like this.
I bought it and am liking it so far. It's an acquired taste, though. One of my main complaints is that you don't have a shared item inventory. Items you get go into a bag and you have to assign them to particular party members if you want to use them in battle. It's not a huge deal, just a little annoying. That's pretty much how I feel about most of the game. No one big problem, just a lot of little annoyances that stick out. If you're a fan of the classic JRPG genre then that's nothing new and you'll be able to overlook the small flaws and still have fun. If you're new to the genre then this game probably isn't one you want to start off with.
