It doesn't fail, it is just a game you aren't willing to put time into. REALLY, there isn't a STEEP learning curve, it is like any other FPS, you have to learn the maps and how to use the tools given to you. And like I said, sure as you play you get cool stuff to use, but they don't start you off with sticks and stones.
$39.99. That is just FREAKIN' awesome. I am willing to bet they will pick up alot of people with this offer. I got mine off Newegg for $47 and was the limited edition that gave you a few items to unlock off the bat, which I never even used. haha.
Yes, when you activate the game during install it asks you if you want to go one of two routes as you mentioned. I hate loading a disk so I picked the 10 installs. I have NEVER had to load a game this many times. even after reloading a system a few times. The 10 different machines, means just that. I have this loaded on my PC and my parents laptop for when I visit there. Once loaded you don't need the disk anymore. Now I am not sure if that means you can load it on 3 times over on the same machine if it craps out and it counts as 1 or if that still counts as 3. That I don't know, however, i am not concerned.
