This is one of the few JRPG's I'm planning on getting this year, and to gauge my interest in it, I was way more interested in this than FF XIII, so what's that tell ya.
I died a few times in the demo, but it was always because I was screwing up how I was going about attacking the enemies, plus you have to use the game field to your advantage while playing otherwise you'll get hit cheaply from the enemy.
I'm looking forward to getting it, when it comes down to the sub-$30 price range (since I almost never buy anything higher than that, with rare exceptions) if money wasn't an issue, I'd probably own it right now, that's how much I thought of it based on my time with the demo.
And I don't say that very often.
Just read the reviews posted, and I think IGN and 1up are fully off the mark, the 1up guy even slagged the music, something EG thought was one of it's best features (as did I)
And as far as their moaning about the learning curve and difficulty level, if I never took the time to learn certain JRPG's intricacies I would have never bothered to play, enjoy and love some of my favorite RPG's such as FF Tactics, Vagrant Story, Shadow Hearts, Valkyrie Profile 1/2 (one of Tri-Ace's own) and Parasite Eve just to name a few that tried something different and succeeded brilliantly.
