After googling "buy starcraft", "buy homeworld", and "buy touhou", I've discovered that you can buy Starcraft and Brood War for $15 from Blizzard at http://us.blizzard.com/store/details.xml?id=110000124 http://us.blizzard.com/store/details.xml?id=110000124 , you can buy a sealed copy of Touhou 6 at http://www.paletweb.com/selectpage.asp?code=00053 http://www.paletweb.com/selectpage.asp?code=00053 , and you can probably only buy Homeworld used. Homeworld's official Battle.net-equivalent (WON?) survived less than two years after the game's launch, but I think you can still play Starcraft on Battle.net. Fortunately both of these games are from an era when devs shipped games with LAN support, so you can play normally over hamachi or garena even after Battle.net and WON disappear. Touhou 6 is a single-player game, so there's not much use worrying about servers.
