My vote's for an Elder Scrolls location. I don't particularly have a preference which (Skyrim works for me; it is the most recent game, and therefore most familiar).

And, damnit, part of me regrets more-or-less permanently getting rid of my ability to go to the moon within the first three minutes of gameplay. Though, wait, I've got an anti-gravity field. That means my thrust-to-weight ratio is [i]always[/i] positive. I wouldn't even need to bother much with orbital mechanics, I can just go in a straight line.* 

Not that, of course, there's any reason for my character to go to any universe's moon any time soon. Maybe later, as the N1-L3 tries to consume Sutternalt's consciousness.

[hider=Babbling]Holy Hannah, that also means I'd have to occasionally [i]thrust down to follow the curvature of the Earth[/i]. Though I guess I wouldn't notice particularly, as any movement at all would naturally account for it - anything interesting is on the surface, anyway. The tiny amount of downward correction would be lost among the larger thrusts to get anywhere. But on the whole, there would have to be a small net planet-center-ward thrust.[/hider]
[hider=*]...I can't decide whether it's more depressing that orbital mechanics no longer applies to me or more exciting that I can still go to the moon.[/hider]
