You wouldn't want to be God. If you were, human perception, human life, human consciousness would become little more than a static figurine by comparison to your own God state. The world and all the universe would become as malleable as clay itself, you could change anything, make anything, alter anything... but from your God state it would all just be clay. The human condition would become no more than a collection of rocks, some brightly colored, some more sparkly than others, but rocks nonetheless.
It's a lot like video games. You can use God level codes in video games to give your character unlimited everything, but then the game becomes rather worthless. You can breeze through it without any effort at all and while the story might be good, the struggle is lost entirely. And without the struggle the story is just that... a story, it's not something you had to work for, not something you had to earn or fight for.
Basically, being God is pointless.
Now, if you want to talk about limited God level powers, that might be interesting. The difference between instantly leveling to 99 and a code that gives 4x experience let's say. In human terms that might equate to giving yourself 4 times the average life span let's say, or giving yourself nearly unlimited intellectual or creative capacity while still have all the other inherent limitations of the species.
