In order to help you get used to your great and phenomenal cosmic power, your game system has locked the majority of your powers behind unlocks and progression through the system. You now start out as a Real lvl 1 player, and can only select for your starting powers up to 10sp worth of power from your purchased powers, you can use this to buy into more expensive powers but are completely limited in what you have access to within that chosen power to the level of 10sp, and can choose a starting quest that unlocks another power at 10sp.
You will gain statistics or attributes that quantify your your current self and your powers, but your system must be progressed through just as much as your other powers.
All powers are locked behind quests which must be completed, these quests are generated via some reaction to something in the real world these quests will attempt to challenge your current power level but should align somehow with the power it unlocks, or they can be forcefully generated through focused meditation. Forcefully generated quests are more likely to be unfair or harder to complete, but no quest will be generated as impossible. If you fail a power quest, that power goes on an unlock cooldown and will take time before you can quest for it again.
To progress your powers and earn more sp worth of their power you have to train or use the powers in ways that push their limits in order to unlock and level them.
