I might get this game in a couple weeks for my bday (I have to choose between so many wii/360 games ARGH) and I just have to know how long it is.

20 hours at the most, and i stretched my run out significantly pissing around with those minigames. If you ran the gamut of bosses, you could easily have it done in 13-15, low-end difficulty.

took me about 13 hours .

I think it took me 12, somewhere in that neighborhood.

Seems to be the same length as the 1st one.
I like the first one, and this is most likely improved, but I only have one game I can get; needs some replay value or something....

I'll see what happens.

Somewhere around 14-16 for me.

Yeah, it's about 12 hours if you do all the minigames and side-missions. You could probably beat it in about 7-8 hours if you just went through the main missions.

About the same length, but you spend NONE of the time driving.  You can instantly teleport to any mission or job or store.  So the gametime is more efficiently action-packed.
