One day you awaken in a white throne room and before you is a gigantic wall. This wall contains texts informing you that you have been chosen to possess complete ultipotence and are to assume the role of God him/herself. What would you do? There are absolutely no wrong answers.
Rules/Notes
1) This would extend to all fictional verses as well and you could freely enter them and manipulate them, experiencing that Omniverse and all of fictional Totality just like Reality.
2) You cannot gain inherit or absolute omniscience under any condition, you must earn knowledge and mastery over your powers.
3) You start out with little control over your powers but through work you can achieve much much more control and flexibility.
4) You may not obtain nigh omnipresence or omnipresence under any condition and are limited to a physical form (though you can freely alter this form).
5) You may give the power to someone else but you can't get it back unless they return it themselves.
6) Assume that Reality is of an atheistic standpoint and is one singular finite universe within 12 dimensions. From there assume that with reality warping creating further realities/dimensions/gods is perfectly possible.
7) You start in present day but you may control time as you see fit.
