I know th change is there, but I never gave a fuck since even the humor is still there and better presented. For example, in the infamous line of "I'm gonna kill Praxis", Daxter asks Jak to say something even though he knows he is silent, and then he suddendly talks. To this day I still think that's comedy gold.
The change was pretty well done. Firstly you're introduced with Jak's voice wanting to kill someone, then guns, and finally, when you actually get to do some Jak and Daxter stuff, you simply can't and you realize you're in a fucking post-apocalyptic future with your old house being burned to death except it's confuding because you find the young version of your old mentor, which was a nice touch too
All in all, the game is not even that edgy the winner for that is the last line of Mizo in Jak X and Jak's following line for what is it and everything it involvescheck 2:20. It's overall really fun and lighthearted even with those little edgy parts.
