Wonder Boy in Monster World is better than Dynastic Hero. The parallax being missing in Dynastic is enough to ruin it for me. The Genesis version was an early release on the system while Dynastic was a later Turbo release that didn't do anything to showcase the system the way it did on Genesis. Plus, the music in the Genesis version is much better - catchier. I had always wished Dynastic had remixed versions of the Genesis soundtrack, rather than new music. Sure, the music in Dynastic is good... it's definitely not bad, but the original Genesis soundtrack is just much more classic and memorable.
Overall, by the time Dynastic was released, it just felt like an okay, but flawed, port of an early Genesis game, with decent new music replacing the even more classic Genesis soundtrack.
When I first saw Dynastic Hero announced, I remember thinking, "Really TTI? A port of an old Genesis game? This is how you're going to save the Turbo?"
