Thanks for the help! And yes, it was a typo, sorry about that
I think for cooling, I should be fine. I use a cooling stand, and I have been able to run Medal of Honor Airborne (the newest one) on medium settings without ever overheating or having any problems. Sometimes it is slow, but usually fine.
Not sure what the recruit-a-friend feature is, I'll look that up.
Thanks again! I think what I'll do is just buy the expansions one at a time (after I get the game of course) and play until I get bored, buy the next, etc.
