I think you had to be there for the cultural phenomenon that was THPS when it came out. It was Wii like penetration. This was a time when gaming was still a hobby and not just an assumed default activity for every breathing person, but it brought over all the kids who didn't play video games. I was a senior in high school and it took over. Really hadn't seen that much penetration since Mortal Kombat. THPS 1-3 are really untouchable. The 3 after that were in the tier below. Anything after that is just cash in slop.
Skate was alright. It never hooked me though.
