Steam just put a lot of relatively unpopular titles on sale, but it's got some really good (if a little bit old) titles thrown in the mix, and I have some funds on my Steam Wallet left over from an Internet giveaway I won months ago. I got:
Each one was selling for around 100 pesos ($1 = 42 pesos) or less. I spent the last remaining funds on Dead or Alive 5 Last Round preorder. They drove down the price and added free DLC to preorders because they missed the release date. I'm not even sure my PC can run this when it comes out, but I basically spent nothing on the games so it's still a win. Plus I heard Dead or Alive 5 is all about bouncing digital boobs.
