I don't really ever remember so many deep discounts on somewhat newer games on PSN or XBL until recently. Same thing for PSN and XBL free games.
This is why every gamer should truly want all systems to have a good deal of success. I don't think MS would give away games if PSN weren't around. Just as I believe PSN wouldn't exist or would be half hearted if XBL didn't exist. Hell, Nintendo might not even have online services unless they had to compete with MS and Sony. We need good competition out there to keep all companies honest and ready to compete.
I really couldn't care less who sells more consoles as long as its close enough to keep the other guys on their toes. Success for Sony and MS equals success for EVERY gamer. Too much success breeds arrogance and stagnation and in the end we all lose. Do we really want ios and android to take over gaming? They are already putting a dent into mobile gaming, if one of the major players drops out of race how long until we are stuck playing all our games on ipads, tablets and phones?
