Let's see how this went
A long long time ago, Microsoft released a game that became very popular. Halo. It was played by many people, and they liked it a lot. It ended with a kind of a cliffhanger.
After a long wait, Microsoft released a sequel. However, they also released a new version of their operating system, called Vista. In order to gather as many unwilling users for their new OS, the majority of which preferred XP, Microsoft twisted their arm and made Halo run on Vista only. If you chose to remain with XP, you got royally shafted.
Then Microsoft released the X-Box. Again, in order for it to gain some traction, they released the final installment -which by then had become a multi billion dollar franchise- on their new games machine only.
So if you'd first invested in the game, then got suckered because you wanted to play the sequel and bought not only another game, but also another OS (and probably new hardware (because Vista turned out to bez a real dog), you were now rewarded by a firm middle finger in your eye : get an x-box or you're not finding out how it ends.
And even if you caved in on the promise of an MP universe, they pulled that finger out of your eye and poked it straight in the other one. NO MP universe.
If you want any kind of customer appreciation, stay away from Microsoft, Electronic Arts and the like. You'll always end up blind.
