I think the additional material makes the book a little more useful this time around to PLAYERS of Dark*Matter ... which can be a good thing ... player books sell better than GM books, all across the board. If players see it as something they can pick up for extra races, feats, options and gadgets to blow stuff up, they'll buy it themselves.
My price concerns are usually moot. I'm cheap. I come by it genetically I think. My grandfather was notorious for being a cheap old fart.
The cover is pretty unique, especially among the d20Modern books, and adds something for the collector. It's nice to handle and comes with that obscure slightly-alien smell of GitD paint. Works quite nicely for D*M.
The expanded player-introduction means it'll work well for my intended purpose ... leaving it where we game as a honey-pot to attract interest. It will lay there, glowing slightly, begging to be handled ... touched ... its tantalizing secrets mere pages away!
Then everybody will get psyched and I'll once more have a regular D*M game! Mwa ha ha ha ha! Mwa hahahaha! Er ... carry on.
