Yeah, it is pretty much the same, and I'm mostly kidding. It's still pretty bad, but there are a few things that make it more palatable to me than Mage Knight.
First is that you're commanding a spaceship flying around exploring the galaxy instead of a fantasy RPG dude trying to walk over the next hill. It makes more thematic sense that a spaceship is a complicated thing where you don't have enough power to fly and fight and beam dudes down to conduct diplomacy.
Second is that the theming, screwy as it is, is much more evocative. A Klingon is different from a Romulan which is different from the Borg. The idea of mana as fuel and card draws as your crew's capabilities fits the spaceship concept, and visiting discreet nodes for mini-adventures (combat) feels Star Trekky.
Third is that sci-fi is -- to me -- about 15% less dopey than fantasy. For the most part, I'm not a fan of fantasy.
But, yeah, it's still Mage Knight. I mean, what do you prefer? A pig, or a pig wearing lipstick?
