Investments often do require additional investments to be made, just do some reading on investment dilution. That occurs, for example, when you invest into a company for XYZ% but someone who pays the same or greater amount later reduces your % ownership of that investment. The only way to retain your position is to invest more. Regarding Destiny - a lot of people have been playing this game either religiously or casually for 6+ months now. If you're not willing to pay more for that experience then so be it but don't complain that there is the option to do. Many people wish to extend their Destiny experience and these expansions are the only way to do so. Some games can be flipped around and completed in a weekend and still cost $60, Destiny has kept some people engaged for half a year. No-one HAS to buy the DLC, also please note the raising the price of the game is an option and it's something Destiny did. You could buy various versions that bundled the season pass in with it effectively meaning you only pay once for future DLC. That option was available for those who could afford it. Anyone of us can at any point make the decision that they've got as much value out of Destiny as they can or they're willing to get and move on. So let's not talk like we're trapped with no way out.
