How good is Jak & Daxter?

[Wagram]

Finished up the collection. Jak 3 is the best in my opinion.

Breakdown:

Jak 1: 8/10

Jak 2: 6/10

Jak 3: 9/10

Collection Overall: 8/10

One thing though: What the hell happened to Keira in Jak 3? She was dead silent, different voice actor, and not the main love interest anymore x.x
