Game for the ps2 like jak?

[HopefulStudent]

Is there any good multiplayer or single player adventure game like jak? I know theres games like final fantasy but what i like about Jak is the unique missions. And most of the game is fairly easy to pass after a few tries. Is there any other game like Jak? and also it doesn't have to be well known just some game you found fun or intresting if you played Jak too. And good graphics is a plus.

And another question I know recently the ps2 is not as commonly used anymore, but is there any game that anyone found iinteresting and fun that they think is worth a try?

Thanks so much!
