Probably don't sell enough units/heavily pirated.
Though when I checked the Halo 1 demo (yes demo) there were over a thousand people still playing it. I think Halo 1 sold well but Halo 2 didn't. That said Halo 2 PC servers are still online so u can still play it online.
I thought for sure they would do a Halo 3 port by now.
Gears of War 1 was a mess on the PC, lots of crashes, bugs, etc. I'm guessing it didn't sell well either.
It's just that simple.
