I found this video which shows it very well:

I liked how there were many similarities to FFXI such as the races looked similar (Mithra and Taru type creatures, not to mention Humes), also the gameplay, there isn't any of that changing to the battle screen, it's directly in real-time which was a big jump.
Oh, and there's also a video for FFXIII out recently. Gameplay graphics are amazing....check out that freaking gunblade!
