I really dont see point of this comparison, Ratchet & Clank is platformer with very small part of rail shooting, Star Fox Zero whole game is rail shooting.
Only thing maybe we could compare is graphic of that small part in Ratchet & Clank rail shooting and in Star Fox, but again Ratchet & Clank works on 30Fps on hardware that is around 5x stronger than Wii U and Star Fox Zero runs on 120 fps on hardware that is around 5x weaker than PS4.

Well, Insomniac Games did make a Star Fox reference near the end of this video.

Nintendo should definitely contact them in the future for a Star Fox project, they could expand the universe with more than just on-rails shooter elements.

all i'll say is rachet and clank is one of my favorite franchises ever and this entry looks fantastic.

The hell is this thread, why would you compare a ugly wii u game vs the best looking PS4 game ?

I don't think he was explicitly comparing the graphics. Just the actual games themselves.

It's even worse, since Ratchet & Clank is a 3D Plateformer and Starfox a 3D shmup

But he isn't even trying to compare the games. He's just asking people what they think about both of them. I assume the reason why he chose those two games for this "versus" thread is because they both have animals in space pretty much.

Here's what he said in the OP:

"What do you think about both? 

Which game will be better and which game will you buy? "

By saying which game would be the best, he is comparing them. It's the same as saying "Which game will be the best ? Fifa 16 or Halo 5 ?". It's nonsense.

When comparing two games the comparison needs to make sense though. Belonging to the same genre is the first place one should start. Otherwise we'd get threads like Zelda vs. Horizon.

People make claims like that all the time on the forums lol

Even though games aren't directly comparable, you can still be able to say something about which game you think will be better.
