Orta is amazing, a total no-brainer for anyone with an Xbox.
I've been playing through the original Panzer Dragoon this Christmas/New Year period (via the Orta unlockable), and it's still a really good game. I actually tried it for the first time a few years back, but that was directly after completing Orta. I don't think that's a good idea, as playing the 20 fps original directly after the 60 fps Orta feels a little rough. I sold that OG Xbox copy and bought the Xbox Live version last month (was happy to give them the money, after all they don't earn anything from a 2nd hand sale). I deliberately left the game playing by itself for 5 hours so that I could unlock the original Panzer, and that was a wise move, as I'm really enjoying it this time around.
I want to play this one, but need to get a new PC, which is pretty impossible right now. Glad everyone else seems to be enjoying it. Looking forward to how Zwei turns out.
