And a sad and remarkable example of what developer neglect can do. Despite numerous pleas on their forums, Blizzard lost all interest in WC3 after WoW came out.
The planned expansion packs were cancelled, major bugs in the client went unfixed for years, including serious maphacks that allowed a few griefers to completely ruin the once-strong online tournament scene and break apart the community.
The WC3 installer won't even run on Macintoshes newer than 10.6.8. Fixing that would be a matter of recompiling it and making a couple of minor tweaks -- perhaps a week's work, tops.
Even if you have an old version already installed when you upgrade your OS, you suddenly find that network games don't work at all anymore once you upgrade - that is, the major feature that you bought the game for in the first place. It relies on Apple's Open Transport networking library, which was removed in 10.9. There is no patch and no fix. The best people have come up with is dual booting into Windows or running Wine.
Perhaps this is why they didn't want WC3 mentioned in the article.
