As already revealed:
50) Tony Hawk's Underground (PS2/2003)
This was something of an impulse buy, quite a while after the original release. I remember hugely enjoying Pro Skater 1 and 2 on the PS1, but I felt that this was even better. It actually had a story mode with free-roam and a narrative that started somewhere and went somewhere! In between all of the skating, across multiple different environments and locales, something was happening. Top that off with a great offline multiplayer component, and I enjoyed Underground enough for it to make it into this exclusive list, if only just.
