Rethinking the MongoCorp Security
As i've understood from the story, the city has been freed and turned to a place precisely for skaters.
Provoking security in the old skate games added to the fun of exploring and skating inbetween challenges.
what if there's a rise of some kind of „skate haters“ or conversatives that want to suck the fun out of the city? like the ministry in Shaun White Skateboarding. As you start the game, the world is cold and grey and you bring the fun and colors back with the power of skateboarding.
Maybe you could provoke them to chase you? Rewards and setting records for time of getting chased and how many are after you, dodging people attacking you, some kind of leaderboard like a blacklist. More difficult line challenges with bearings in „danger zones“.
Trick mechanics to defend yourself on-board, Maybe with footplants or the judo grab. In the old games your arms and legs would bend to tolerate a little collision with the world instead of bailing. I'm guessing that would be difficult to develop without glitches, but in my mind that could be VERY fun if done right.
