I love Lightening Force,its def a paralax benchmark,and that really adds to the visuals alot,but I still think Rayxanber 2 and 3,and Gradius 2 look better,not worlds better,but enough.
Takara was a great company when it came to doing what they could with Neo ports on the Genesis and Snes,I don't think it was ever a lazy factor that came into play.Proof of Takara working hard shows in AOF,FF Special, and World Heroes 2 on Snes,and Fatal Fury 1 and 2 and King of the Monsters on Genesis. I think the Pc-Engine just had it better at drawing and moving those kinda sprites though,the types needed for fighting games,much easier then the Snes and Genesis. I think infact SF 2 Champ would have been much better if Hudson worked on it then Nec,as Hudson prob would have strove for a better port while Nec seemed content to just match the others more or less. Proof of that def shows in the Hudson Neo ports. Its also nice to point out that Gradius 1,2 and Salamander on PcEngine are better ports of those 3 then Gradius 3 on Snes.
