No wonder the world economy is in such a poor state when individuals consider that buying a game/simulator is an investment.
Quite the opposite: The economy is in such a sad state because people have been too cavalier and irresponsible with money. Especially other people's money. I think it might be threadjacking to go into this into detail here, but one doesn't have to dig too deeply to see that such irresponsibility is almost the universally cause of such problems.
As for the need to change the system (and we're also almost certainly not limiting this to DLC, at least in the future,) their position is that, in some parts of the world, piracy is rampant due to much lower household incomes. That really should not be a surprise to anyone, and I expected that reply. I'm sure we all know exactly what 'parts of the world' they're talking about. But, the problem is, exactly the point N3V made: In many parts of the world, incomes are low. Many people just can't afford a $60 game or even a $20 one on sale, let alone $20 DLC. So, they'll obtain bootleg copies. But, they fail to see that few if any of these are really lost sales, because those folks wouldn't have been able to afford a legit copy in the first place. Not to mention are quite adept software crackers, rendering the entire exercise moot.
Yeah, we've all seen the posters who post with unregistered versions. I don't help them, and most people don't. And, if N3V uses a half-decent serial-number registration system, folks with stolen, cracked or keygen'ed serialz shouldn't be able to access the DLS.
I've also done my share or reporting and removal requests when I find suspected pirated Trainz material. All told, between the value-added service of the DLS and the community activity, the DRM was really an unnecessary step. But, judging by the lack of mention of it in any of the patches, hotfixes, announcements, and so on, it seems likely they thought they could slip this one in under the radar, and it was only after much heated discussion and grilling did any details become public.
Interestingly, they STILL seem to be attempting to deceive purchasers of the NKP DLC of that fact. Go take a look. I'll save you the trouble of finding a direct link:

Sure, they mention that you need SP1 to initially download the pack, but do you see ANYWHERE a mention that you need an internet connection, even if only a periodic one, to continue using your purchase once downloaded?
