PoP:classic is maybe one of the best "retro" redone games on XBLA. I wasn't too impressed by Pacman:CE, but I did like Jetpack Refuelled
The animation and moves in PoP:C are fluid, and he has new moves like the backflip, and the jump off the wall; grab the ledge behind. The combat is pretty difficult at times, if you screw up, they can get a double combo on you. The final blow animations; the one where you stab the lost sword into the heart, or kick him down is pretty good. What you want to do is lock swords and tap X repeatedly, and win, the prince punches the opponent in the face and you can do a 2 hit combo (ftw)...
I find this game pretty tricky, and I would say I was pretty good at the original, and the flames, and sot...
Worthy of your time and money
