The Culture. Drug glands, total and unlimited freedom, total control over your genetic code (you can impregnate yourself and give birth to your child), 400 year life span(They only die because they choose to), extremely low danger of death, every luxury you could ever dream of at your beck and call, and living in a universe filled with other intelligent species. It is heaven.
To me, that would get really boring after about 6 months or so, because there'd be nothing to spend your time on.
Hmm. . . Speaking of wasting time, Maybe the Minecraft world? that could be fun, not having everything instantly available, but having most of the limits to sheer, uncomplicated construction removed.
