The classic game, but even better. HD brings numerous bug and balance fixes, and lots of new content to boot. It also brings Steam's interface which facilitates multiplayer. The Forgotten expansion even makes Cartography a free tech that researches immediately after you click on it!

And remember!
Roses are Red.
Wololo!
Roses are Blue.
