Ah, the memories. Back in the days when Microsoft could be openly and blatantly anti-competitive and nobody really cared because it was just perceived as a nerd-fight outside of tech circles.

It was just a coincidence that MS decided to make some changes to Win95 that made it depend on things in MS-DOS that DR-DOS didn't have, but then when DR-DOS caught up, they still had Win9x complain about "incompatible" DOS.

But somehow MS managed to maintain backwards compatibility with SimCity. https://news.ycombinator.com/item?id=2281932
