(But that was before they started their UPlay "always online" nonsense so no guarantee it will happen again on more recent game.)
That is true. Then again, they aimed for the same thing they do now - to bring the gamers and with the account bind them. In case of FC2 it was with DLC packs, Anno reintroduced the limit with the addon.
And now we have their stupid system of always online DRM and the idiotic uPlay business. They won't stray from that until it's too heavy on their purses. Which I hope is before BG&E2. That's why my question might have seemed surprised, the SecuROM thing kind of faded out behind the noise the uPlay/UbiStarter thing makes.
Anyway, this was supposed to be about New Vegas. I think the actual reason for using Steamworks is some kind of protection for the DLC files - those were probably even easier to pirate than F3 itself. Just a hunch.
