So I finished my playthru an hour or so ago, I quickly ran back up to the lake fight because I missed an achievement, and wanted to see how much quicker it would be just blasting everything while not breaking pace. I know some people can finish the game very quickly, but I'm not one of them, it took me 36 minutes to get to the lake.
Anyway, I finished it, and it was as incredible as ever, the bulldozer is still kind of lame, as is the final boss/jet-ski, but it's as close to perfect as an action game has ever been for me. I did fire up Separate Ways, the FMV looks really crummy, not sure I'll finish it, because it wasn't so hot if I remember correctly, and the FMV thing is annoying, but I might.
