Never. The promise of becoming interesting is there purely so your hopes can raised and then crushed like a boulder falling upon a human child.

Well I liked it. It is just a game that gets boring if you play it in long sessions. I picked the game up a few times a week and ded one or two missions in a session and it never went boring for me. It gets better when you reach the next map when their also will be some new kind of missions like protect a boat. Destroy a fucking bridge(loved that mission).

a boring mess is what that game is.

just drive from point a to b kill everything,,,rinse and repeat.

I never tried the multiplayer. I figured if the single player was that awful, the multiplayer would be worse and I would chuck my PS3 out of the window.

the only thing i enjoyed was making my own map online

I only played it in short sessions and found it very boring.

+1

Never. But I only played it for 1 or 2 hours then gave up.

No it was a horrible experience.

I completed it, thought it was pretty poor. The story doesn't get any more interesting really.
I did a review of it (link in sig), so if you want my thoughts just read that.
