Alright, this isnt really fair, Ive taken a really old quote. Im gonna help you guys out a bit. Quote of the same user only a bit more recent.
In the end it could be simplified to long-term investment vs premium entertainment. Halo was one of those FPS that really stood out from the rest though. The Halo universe is interesting. It had an interesting plot if you paid attention to it. I got a lot more out of it after watching an animated shorted movie of it.
