Fun is of course subjective. Some of us care about realism more than others.

I think we're all aware of that. The post you're responding to essentially made the same point you did, but to someone who thought it appropriate to express their love for realism in a much less mature way.

I bet some do, but not enough for anyone to ever make a commercial game that focuses on hyper-realistic, multiplayer space travel.

It's going to be such a fun game flying 1000 lightyears at a couple hundred meters per second.
