Super Street Fighter IV Arcade Edition has been a PS+ freebie before, but has never seen a heavy savings on Steam before today. Until mid-day tomorrow, you can get it for 75% off, taking it down to $7.50. You can also get the complete edition of it, with a boatload of DLC for only $12 – making it the better overall value. If you’ve got a strong enough PC setup to run the game, this may be the best way to get it for a low price. It’s certainly hard to imagine it ever dropping below a 75% discount.
