I just got this on Monday and I have already sold a million boards and completed most of the challenges. It seemed like the previous two took way longer to get through than this one. Is this because the game is much more forgiving and open than the first two? How far are you into game?

It's all about the online.

Really? Man, I rented it yesterday and was afraid I'd have no chance of reaching the end. It looks like an awful lot of challenges to me. Well, this is good news for me since I have no intention of buying it. I'm currently not far. A 2nd guy just joined my team.

You can go back and try to 'kill' every challenge.

I have 8 Hours of play time and all I have left to do are 4 own the lots and like 6 own the spots everything else is done.
