My gf played the Jak trilogy on the PS2 and while she really enjoyed the first game in the series, she absolutely hated the second. What is it that you like about it?
I finished the entire trilogy on my PS2. All games are great, but I feel like Jak II is a huge improvement over The Precursor Legacy. The dark atmosphere, and the open world are so much better.
Jak 3 is great too, but the second game had a bigger impact on me.
