Lol, Mystic Formula was an example of a hallway walk 'n gun like Skeleton Crew. Again, it sounds like you're just taking my misinterpreted word for Mystic Formula being "as close as it gets" because you are so obviously unfamiliar with the PCE library. For Skeleton Crew times ten, see Sapphire.
I thought you knew what the PCE was capable of because you "have all the games"?
Depends on what you mean by quality. They aren't even remotely the same genre. I don't want to have to criticize Genesis games just to point out the obvious in extreme ignorance of the PC Engine's strengths. But Blood Gear has graphics that the Genesis can't do, period. The PCE can and has done most of Ranger-X n different ways, but even the most different looking substitute that would be required for one element wouldn't be nearly as big a hit as the difference in color/shading/detail that is possible. The horizontal shooter sections aren't anything that hasn't been done in PCE games, only with better color/shading, less slowdown and likely the same amount of flicker.
The PCE couldn't easily do the multi-directional stages's parallax the
exact same so easily, but given the style, a simpler substitute (
done like 4:00 in this video) for the often abstract art wouldn't look too out of place at all. The massive upgrade that is possible for color/shadsing/detail for everything else would certainly help make up the minor loss). Ranger-X is still a neat game, but it emphasizes the Genesis biggest weakness as much as its strengths.
You seem to have "rose colored glasses" as you count everything "the PCE can't do" yet still ignore everything that the PCE can and has done that the Genesis can't. How are World Heroes 2, Sapphire and Fatal Fury Special "cute"? Because the sprites are so huge, detailed and smoothly animated against backgrounds unmatched outside of Neo Geo?
You once again sound like a youtube commenter insisting you know enough about the library to dismiss it, yet only mention the most well-known games. If you place no value in actual graphic quality, horsepower, sprite ability, etc, that's fine. But all you're demonstrating is that the few PCE games you are familiar with don't suit your customized tastes.
Filling the screen with giant scaled sprites that would require six SNES systems worth of Mode-7 is only "interesting"?
