Because the damn game is good, that’s why.

It’s been out forever so no bugs. It’s passed the test of time so it’s entertaining and has interesting decisions to make. There are mods and user-created scenarios. Who the hell cares what it looks like? Jesus, people.

And yes, I realize that there is a substantial cohort of those who play games primarily to (1) gaze at graphics (2) get a consumer’s sense of satisfaction knowing that the graphics card is pushing billions of operations per second.
