would this be the future requirements for games? they make you register online to play the game and if you buy used you have to play 20 dollars? 

i think it will because all three companies have an online service that can handle this. 

Well for the online experience I think personally think that the future will indeed be tying your PSN and XboxLive account with another account from the publisher or developer. Pretty much the same thing you do with EA games, steam and battle.net 2.0. That way they have a better view on who is playing their game, hacking and what not and also you can't have multiple CD-keys playing online at the same time.

I think it will be tough because if one console decides to make it harder to buy used games then the other console will surely get a huge boost in market share over the other one. It will have to be done collectively to work but this might be a situation where competition in the marketplace will prevent this.

See I doubt this will work at all. They have tried this on PC games, and every time they put such DRM, people just pirate the game more. I am probably giving the average console consumer a lot of credit here, but I'm hoping they won't stand for this type of shit and just pirate games with such DRM even more.

The reason for buying used games is for it to be cheaper not to have to pay a extra 20 to actually play the game

I think this is a test run on whether or not people will do this -- be willing to "rebuy" on-line play.
What it does though is effectively cut the value of what you have bought -- if you go to resell/trade the item.
It is another step down a slippery slope to games not being owned but having perpetual play licenses (which can then be pulled play licenses).
That being said, given the levels of piracy that supposedly occur on the PSP, it is worth trying something like this. Of course, my guess is the pirates will crack it soon enough.
