Oh Sony, you so funny.
After announcing today to huge applause that the PS4 would not restrict used game sales/trading/lending etc, and have no online check every 24 hours, Sony has continued sticking it to Microsoft with an instructional video on how used games work on PS4.
I expected that Sony would allow used games after seeing the response from gamers to Microsoft's strategy, but I didn't think they'd go so far as to use it as a marketing scheme. I was wrong! Check out this awesome video featuring Sony's Shuhei Yoshida.
