Honestly, I feel like I get carded buying mature games as much as I do buying alcohol. It's funny to me because there's a four year gap from the 17 for mature games and the 21 for alcohol, but in my experience mature rated games are checked as frequently despite my being 25.

There are solutions to this that game companies could examine. First, the game companies could realize the true potential of digital distribution. We know that they save money by not having to go through production of hard copies, yet almost no platform but Steam gives any discounts to this effect, and the Steam ones are sporadic. Lowering digital prices over hard copies would block transfer of games, increase profit margins, and encourage buying new over used if the price is less than the hard copy. Second, pre-order bonuses are usually my main incentive for getting a game when it releases. This could be extended for new games, so that there is some bonus. One way of doing this would be for games with DLC to have one or two included free with a new game purchase through game registration. There are other options, but the truth is that the choice of which type, new or used, usually comes down to basic economics. The same good at a lower price is the one that sells best, unless some incentive negates or overcomes the cost differential.
