God, I can't stand the VA in Adventures! It makes me want to kill myself! Not even kidding, whoever did the casting should go crawl into a small hole and die, right now. AGH!
I liked the voices in Assault, although some of them seemed too much different. Peppy wasn't southern, Slippy sounded like an 8-year-old boy instead of a girl, Falco just kind of lost his arrogance he had in SF64. "Me? I hate cold." SF64 Falco would never complain about the cold. And Leon just sounded ********. Sgt. Johnson+Leon Powalski=epic fail. Scully was alright as Panther, though. But they should have stuck with the traditional VA style for Leon, everyone liked him better that way.
Actually, Grant Goodeve as Wolf was the only voice in there that I thought was above average, even though I liked British Wolf. It was a good voice-over, but still too different for my tastes from the original. I think Cam Clarke should voice Wolf, but that's just me.
