I stopped playing internet games when I came to realizations. For example, when I played Eve, I initially thought it was a free universe of opportunity and everlasting success until I realized that it's just mimicking business and success we could be doing in real life, not to mention the world falls under CCPs rules, not through innovative discoveries real people would make.
That aside, spending all your time and effort running a corp and getting money never has a satisfying end. What do you do when you get to that point where you have all the money you need and want? You just keep playing the game, and there's no end bonus to be had. One could say "fun," but is a mining corp really fun? Is a wormhole racket really fun? Is killing people all the time really fun? Well, yes to the last one, but it's also the most risky, and you get to a point where your power is so overwhelming you and your corp could take on anyone. Yet at that point, what's next? Every MMO is about what's next. Once I find the answer to be "nothing," I move on.
