Who said anything about not being able to play it? If I can run a game with wizards and elves I can run a game with warp engines and phasers
Where did I say you can't play a game just because it has magical technology in it? You should see some of the stuff I have thrown at the players in the Culture setting I run every summer.
The issue is if the magical technology is applied consistently - the law of unintended consequence may as well be added as the fourth law of thermodynamics...
(yes I know there are already four laws, zeroth, first, second, third, so the next one is the fourth even though it is number five)
