Do you agree with companies trying to rid used game sales?

Should we get rid of used game sales? Absolutely not.

I think the way we're currently handling things like online passes is a bit flawed (nobody likes inputting codes), but I have no problem with the idea of online passes themselves. As for used games, also no problem with those. If people want to buy and sell used games, let them.

See I can somewhat agree with this view, but what I don't get is Single Player Online Pass (it even sounds like a contradiction.) 

Originally it was Mass Effect that had DLC locked, unless you had the pass, but now it is on-disc quest content being locked away. The next evolutionary stage would be to have huge section of the main story locked with a pass. 

I'm not familiar with any single player online pass sort of system, can you give an example of a game that uses it and how?

The only thing I can think of is Rage which gives players access to only bonus areas which I was pretty fine with.
