It's not hard, once you level up. Fully leveled I can blow through the game in roughly an hour. It's a really fun game, I only had it freeze up a couple times, and they fixed the major Store bug that was around when the game launched.
Ok, good to know. I really enjoyed the comics (haven't watched the movie yet :\) and am interested in how the game plays. I'll see if I can call them to buy the game during the sale!
Your account is on hold?
Yeah, it sucks... I loaded 4000 points on my account a few weeks ago, and of course about a week later 3200 or so suddenly disappears. After a bit of hunting on the terrible Microsoft/XBOX site, I found that someone used the points to buy Sims 3. Still not sure how, since you can't download it to the Xbox as far as I can tell.
Customer support was really pleasant and said they should be able to refund me, but it'll require that my account be on hold until the investigation is complete (up to a month, blegh!). So anything that requires me to log in, I can't do.
The most annoying part is that there's a competition for highest score going on for the Paranormal table on PFX2, and I can't participate (with my gamertag)!
