I've been playing the NFS series since i got my PC, back on 2004. I've literally played everyone of them until Pro Street, since my PC isn't powerful enough to handle the rest of them(Damn and i want to play NFS World so badly,lol).
Anyway, my personal favorite is Most Wanted, mainly because the cops are actually hard to beat on the higher heat levels, and cause it's story is the longest and most interesting. Modifying the trax so that it plays only Decadence
and spending hours in front of our screens was a kinda sick hobby of mine and Zeus198 back then
. Carbon was cool too, regardless of what some people on the net say. It introduced the actual tier system and gave performance limitations to cars, something that Most Wanted did on a minimal degree, and was its only drawback. Carbon's main drawback were the easy cops, as getting a 3M bounty was really easy.Oh, and canyon drift ftw. Underground 2 was ok, though it was more about pimping your ride than racing, and no cops to ram
. Prostreet introduced car damage, though that was all about it, and i could actually drive my beloved Camaro
on a drag race, smoking Shelbies and Supras. Games like the original HP and the rest of them, were ok, not as exciting as the ones i mentioned above though.
Also i once wanted to play Burn Out Paradise and Grid , though my PC failed again,lol.
