From the review:
"Still with me? Good. For everyone that's played Culdcept before, it's plain to see that Saga is really just Culdcept in a high definition wrapper (and even then, the graphics are very basic). The gameplay is exactly the same and a good portion of the cards were first seen in the original game. But it's through the use of the cards and the battles against other Cepters that the strategy and obsessive detail of a game like Culdcept shines through. It may be very similar to the first game, but for someone who was begging for more after the end of that game, more Culdcept (and all that comes along with it) is welcome."
