Yeah trust me difficulty is totally irrelevant.

I will gladly tell you the reason why I quit.

I no longer like the guns I can use. They are too sugarcoated to be any threat. How is a gun with a kiddy beam that doesn't look even a little bit threatening fun?

I will admit I still find the silliness of the enemies funny.

But the rabbits who are the protagonists are dull and have barely any personality.

Say whatever you want about Superman but at least he has personalities beyond just one brief personality. Spaz and Jazz have none. And I'm only judging it on what I can do in these games, the cartoony intro is totally irrelevant.

And why would I want to play the earlier games if I don't even like Jazz or Spaz? I wouldn't that's the thing.
