Some very uneducated and blinkered statements. Take a look at the two, a proper look, try to lose your american loving glasses for one minute and actually compare it.
If DH was infact better, I would play it. Adding nice features to a bad game still makes it bad. Some maps are nice but most are not. The new weapons are poor and at a level expected of a mod.
In conclusion the Mod looks and feels like a mod. Roost feels and plays like a proper game.
This sounds like the kind of crap you read in reviews of Red Orchestra and Killing Floor.
Notably:
"There's little doubt either that Killing Floor is rough around the edges - it certainly still feels like a mod, albeit one of high stature. You can leave your fancy physics objects and clever-clever lighting routines at the door. Instead it's the sort of game that isn't fussed about frippery like polished presentation, and will quite happily throw in a few user-unfriendly interfaces in the knowledge that, as a PC gamer, you'll have come up against worse.

If there's one thing Tripwire's games lack, it's polish. They have beautiful first person anims....but the third person anims leave a lot to be desired. They have beautiful gun models....but the environments leave something to be desired. Functional, but unattractive UI, and so forth.
I mean, frankly, from what I've read of the DH physics engine, it fixed a lot of RO's issues, and notably they FIXED bugs. How does that entail that it's more of a mod than RO? First person anims are grossly inferior to RO, but many of the weapons are fully realized and considering the undertaking, it's just straight up rude to disrespect them for their effort.
If you think that budgets and polish are such an enormous issue, maybe you should go play Killzone 2, which had a budget exceeding 40 million dollars for
development? How about you play Call of Duty, which receives enormous marketing and development budgets with one of the most comfortable professional developers in the business?
Oh, that's right, because some things are more important than polish. Particularly considering that MW2 suffered from a plethora of bugs and networking issues and didn't give us mod tools on any equal level to the ones we get with TW games. But, ooh, that menu sure is sparkly and pretty.
