1. We don't know how much the games will cost or how they will drop in price compared to now with this new model.
Technically no, and I suppose MS could surprise us by running frequent MEANINGFUL sales sort of like Steam. The DRM is pretty much just as bad as Steam (other than the much more restrictive offline mode), but people forgive Steam because at least you can get games for really cheap if you wait for a sale.
Can't help but think that, by restricting used games to "participating retailers," they're creating a situation where a small number of shops will be able to set prices without any real competition from smaller, independent sellers on Amazon and eBay. Basic economics.
2. People who complain games are too expensive and offset the price by selling used, probably haven't made the wisest of investments in purchasing a gaming console. They would be much better off buying a PS3 or 360, due to it being overall cheaper and a ton of games are available for cheap.
Ah, so it's another "if you want to save money then you must be poor" argument. Please stop this, it makes you look like a complete asshole.
3. I was trying to highlight the absurdity most people are arguing against MS, despite them actually giving us useful features in exchange for this DRM / license model.
MS should be going all out to promote the actual useful things that you can do with the Xbox One, because there are at least a couple. The family sharing thing is nice, although allowing up to 10 people in a family circle belies the usefulness of the feature. If only one of those people can share a game from the "leader's" account at any given time, it doesn't matter how many people you allow in a circle. Still, it's something you can't do with any other console as far as I know.
The other useful feature is not having to get up and swap discs, but that's pretty minor. I can't remember if there are any other nice features resulting from the DRM.
