I could say I'm one of those people.
While it does feel more like you're progressing in Jak 3, I think that Jak 2 had an overall better story, even with it's odd pacing at times
especially noticable in the scene where Praxis dies.
I also like the world a lot more in Jak 2. Yes there are the Krimzon Guards that limit the fun you can have, but in Jak 3 there's either a fullout war happening around you or a boring desert with nothing to do.
And Jak's design is also better in Jak 2. I know this sounds weird coming from someone who can defend A4O's designs, but I can't stand how Jak looks when he has the full set of armour.
What's weird is that armourless Jak looks really good.
Look at it, how does he move?
