Keeping with the trend of evolving in each entry, Underground is the first Tony Hawk game to introduce a story, and a surprisingly good one at that. It's nothing spectacular, but I think it's fair to say it's a lot more competent than anyone was expecting of a skateboarding game. The gameplay feels smoother than ever and is, once again, complemented with more new mechanics like getting off your board and wallplants, and some smaller things as well. It also added some more polarizing things like the vehicle missions that, even as a kid, felt out of place in the game, but there's only one per level so it isn't too bad. Complete with one of the most annoying video game villains of all time, THUG is still a very fun game to this day.
