Voices I think Are Well Done
Radec (although his voice modification is different from KZ2)
Voices that Need Improvement
Kratos (he has some lame and cliched lines and his voice isn't as great as GOW2)
Jak (apparently a different voice actor, never really played Jak games)
Daxter (honestly in my opinion kinda annoying)
Sly Cooper (has lame lines and is a little too excited. A lot more calm and cool in Sly 2/3)
Cole MacGrath (bit quiet)
Voices that are BAD
Fat Princess (very annoying to listen to)
Parappa (this might upset people, i know, but very annoying to listen to. Sounds better in the original Parappa game. Plus his VA isn't even professional. They should infused his personality with modern hip-hop/rap slang and such. Interestingly enough, he has a placeholder voice clip in the E3 build which sounds much better)
Spike (I think they intentionally made him sound like a badly dubbed anime char)
Just my opinion. I may have missed people, mainly if they're mute or didn't really stand out as being good or bad.
well parappa's voice actor aged and he even said that hasn't doesn't voice work in a long time. Spike's voice sounds a bit weird especially when he gets hurt, but he never got an official voice actor so can't complain there. But hopefully they improved all of the voice work by the time the game is finished.
I'm bummed out by the fact Anna Torv isn't doing Nariko's VO (Fringe of course)
and Kratos doesn't say I AM THE GOD OF WAR!! , none shall defy me, i will make you suffer (should have just ported his lines from the begining of GOW II)
