The game corporations will claim that there is no right to play, and maybe even insert a clause that means roughly that into the EULA. It is their right: if you don't agree with their offer, don't buy it! There are more good games around than you can possibly play in your free time, and there is no lack of other entertainment options either, so please stop whining.
There have always been (and there will always be) shitty or crippled products. Or even otherwise wonderful products that have one huge defect. There will always be stupid managers and lazy engineers. Just walk the other way, don't stick to them - life's too short. In this particular case, every single slashdotter knows that DRM is bad (if you don't, please hand in your geek card on your way out). Do we really need to revel in its failure every single time a major game studio screws its customers?
