But remember stream accounts are free, around 50-60% of those XBox LIVE accounts are paid for.
ahh, this I did not know. but ps3 is the same way and even allowing for multiple accounts they just passed 30 million.
in any event it's still a smart move. VALVe offers a lot of great content through steam and are big proponents of understanding market trends and satisfying CUSTOMERS. not screwing them over with DRM that only hurts paying customers or raping them with high prices. I've always been impressed with VALVe's foresight and development (not so much their time schedule but, meh).
