While I do agree with some points the previous reviewer has made, I do have a few opinions that vary as well.

I understand that a lot of people hate the way Jak II went Darker And Edgier, but I am mostly for the change - the first game was good, if but a little short but the second game introduced some really cool mechanics like the guns and the hoverboard. Plus I can see why it's unsettling to see Jak hold a gun, but I feel that its purpose of efficiently killing enemies outweighs that feeling. Now I said I was mostly for the changes, but looking at it now that I'm older, I do have a few complaints. Haven City is way too hard to navigate for a hub world, some of the dialogue is narmy at times and some of the characters are rather annoying. Again, that's just my personal opinion.

Other than that, II is notoriously hard at times and difficulty spikes come out of nowhere. But I'd have to say it's a lot more polished than its sequel.

To me, 3 is a bit of a joke and where the series began its dark descent. Though it introduces even more mechanics like the buggies and even more gun upgrades, you can tell the game was made in just over a year: there are more plot holes, questionable moments and retcons than you can shake a stick at; some of the mechanics (such as putting away the gun) and environments are buggy which could've used with some tweaking and there's even more Narm in the dialogue (Jak pushing Erol off of that edge comes to mind). Though there are salvaging moments such as hilarious The Reveal and a certain character's death.

Jak X to me was godawful. The learning curve felt too steep and I felt bitter for losing a race just because I got killed just as I was about to cross the finishing line. That and the rumoured glitch that corrupted your memory card made me put it down for good. At least it fixed the Big Lipped Alligator Moment that was Ashelin's brief hookup with Jak.

And I agree that They Just Didnt Care when it came to TLF. It was like High Impact games tried to target a younger audience for a world that is definitely not kid-friendly. Each to their own I suppose.
