Yeah, Wipeout HD and Pixel Junk Monsters are free for just this week only. I think the sale ends on Sunday.
They are not free... dunno where your getting your info
You didn't get the e-mail from Sony?
Tekken 2 could have been free. Its a great game but eh still think it could have been free. One game they could offer for free is Air Combat that game is fun and very very short. I beat it within a matter of 30 mins to 2 hours in 2002.
P.S. Sorry pal no free full games on the PSN. Free demos and game trailers. If you like wallpapers for your PS3 then yes those are free also.
