GameTap, like many other PC game download services, has the full PC version of Street Fighter IV available for download and purchase (and no, the game is not a part of their game library that can be played via their monthly subscription service). To celebrate, GameTap is offering one of the older games in the fighting series from Capcom to play for free.

The Flash-based browser game is Street Fighter II Championship Edition and can be accessed if you have a free GameTap account. There's no word yet on how long this promotion for Street Fighter IV will last nor how long we will have to wait until Street Fighter IV is added to GameTap's subscription service.
