there was nothing particularly surprising
why would it be surprising? I mean, aside from the fact that it doesnt suck. 40k the tabletop game has a lot going for it - it's artistic, you have to mentally juggle a lot of stuff to be a good player, and its very social. All good things. But what it doesnt do is go "boom". Sure, you can imagine it, but it aint the same.
This video game, otoh, goes boom very well indeed. I think what's exciting about this game is that Relic, a third party games developer, seem to have really understood what 40k is about. Dawn of War was the first time I had seen 40k done well. I mean, when you play 40k on the tabletop its all very abstract. "Ok, the broadsides are shooting those Leman Russ. Right, 2 4s and a 1. reroll for twin-linked...blahblah."
Dawn of War did this:

Sure, the graphics for DoW aint so exciting, but it was an RTS, so visually it was more about having many units on screen at once. Space Marine has raised the bar graphically a hella lot.
Another big improvement over DoW is the tone of the game. As the reviewer says, the developers calmly and deliberately made an M rated game. No mucking about here - chainswords really eviscerate bad guys, bolters blow em into little gibs, and there's generally a lot of blood all over the place. Thats what 40k the table top game can never do - get visceral. And that is why this game is exciting - it fills in some of the missing pieces of the 40k experience.
This game needed to be good. The future of 40k's growth is in video games and movies. GW are sitting on a potential goldmine here. Maybe you don't play video games, and thats fine, but in recent years video games have made far, faaaaaar more money than movies have. I kid you not. You wanna be rich these days? Make a video game. Sod all that hollywood malarky.
GW are a miniature wargames company. Good for them, but to really get rich (which is not actually a bad thing, I think. Successful GW = more 40k stuff. Good for us, too.) they need to use their biggest asset: the Warhammer 40k IP. Not the miniatures - thats never going to be a really big earner, but licensing the 40k IP? Hell, there be gold in them thar hills and no mistake.
This game, I reckon, is the tip of a potentially very cool iceberg. More 40k games. 40k movies. 40k TV show? 40k books by proper authors? I dunno, but the more the merrier, I reckon
And that, in short (ok, not that short) is why this game is exciting.
