Purchased this a week ago (2018). I had to use the old "dx2" executable, not the "dx2dx" which would not load missions at all. Even that was quite crashy and unreliable, very hard to adjust the graphics options, but I got some campaigns done and experienced the basic gameplay. I don't recommend playing it long term. Origin also offers the title, but as their download platform is worse I can't compare the two versions.
