Back in the days of multiple floppy disk installers, Dune II is one of the first RTS games I’ve played on my 386 and is probably one of the successful ones that started the genre.
You can play the campaigns of all three houses: Atreides, Ordos and Harkonnen with each having about 6MB worth of download. It’s best played on your desktop since you can make use of the hotkeys and left/right mouse clicks, although you can also play it on Android and iOS devices.
It crashed my IE10 Release Preview but it was fast when it was running. Chrome is a bit slow but stable. Response is not that good when played on a Chrome browser on the Cherry Mobile Flame but still playable. Chrome for iOS crashed on my iPad mini after the opening scene with the Mentat.
