There are many quests in Final Stand Remastered that you can do to level and master your skills as well as unlock new locations, moves and forms.

Quests are separated into 2 categories:

Daily quests (?) and One-Time Quests (?)

You can differentiate them based on the color of the question mark.

List of Daily Quests

There is a mysterious mechanic called “Potential” where players have a hidden stat of the same name, that will determine how much EXP you earn that day. Doing quests normally will earn you a set amount of EXP, however, if you enter the Hyperbolic Time Chamber when you turn on the game each day, and then proceed to complete quests and defeat NPCs/players, you will earn way more. This is the best way to earn EXP outside of PvP(ranked) and raids.
The quickest daily-quests you can do is all the West City ones, since the quest giving NPCs are right next to each other.
The Milk Delivery questline can be trivialized by cutting through the canyons and using the Motorcycle capsule, since it only says no flying, which means ground based mounts can still be equipped.

List of One Time Quests

Will be added soon.
