What Power Would You Want In an E-Sekai

The God has spoken, you can have any power in this new world. What would you want?
A magic pocket that you can pull anything at any time? A library of knowledge that you can learn anything and everything from?
The power to control elements? The power to foresee the future?
Interestingly, this question is something that I got myself asking. I mean, I could ask for anything, right?
You could provide a full description of your capabilities, like a DnD character lore.
Honestly, I have never played DnD, but I assume that if you created a character without downsides, that it wouldn’t be fun, right?
A perfect character that has a counter for everything, then that wouldn’t make a balance game, right?
When is it apt to be content and wanting to strive for more?
I think adaptability is one of the best powers we can have. As time passes, we want to be able to mold our environment to adjust to levels and create a process of redistribution. This can create a balance that would make the experience fun and fresh.
I think that the striving for more can only happen if the environment encourages and creates space for improvement. Contentment only happens when struggling does not create fruit, which makes the entire endeavor meaningless.
When coming into an isekai, the general trope is for the main character to be overpowered. This essentially makes side characters almost irrelevant apart from adding flavor and color to the main character’s story. While the MC can essentially run the show himself, we often find him/her encountering characters either by choice or by chance. Generally, evolving or growing characters make the story more colorful and create a more balanced world. So while being overpowered seems the ideal choice at first, having other people join in creates a more unique and bright story line.
