Many things will be more complicated in Star Citizen than usual in other games. The health system is only an example of this. We've also seen that racing will require real commitment to be part of the best. I think we'll see the same with other parts, like mining for instance. Key word here is skill. As far as I can see you won't be able to have three or four professions if you want to be best in something, or perhaps even succeed in the competition. You'll have to consentrate on one thing.
This is one thing that will set Star Citizen aside from other games - skill, in every profession / task. Plus the game will also have many genres into one game. Many players today are used to games with one or maybe two genres, and fairly easy handling of each task. Star Citizen will be very different. Richer in variation, deeper in skill, and more immersive in how you need to handle things. Instead of just point & click to obtain rewards almost magically, you have learn how to do be a miner or explorer or info agent or racer, before you can master it.
Many won't like it because they're used to having things more easy obtainable, and play games that last only a few hours before you can "win". Then again, many of us have waited a long time to play a game that's more challenging because it's more rewarding when you can finally master something, after lots of training. I think this will attract players after a while, when they see how diverse and rewarding each task can be. But this is my opinion.
So skill? Do you know when they are going to add it to the, so called, dogfighting? Because the current chase the mouse, FPS style, flight assist, flight model has a very low skill cap. Seems that CIG like to add complicated sounding system then add easy mode gameplay system on top of them.
