Sony's Welcome Back celebration is just about over; they're sweeping up the floor, stacking the chairs on the tables, yawning a bunch, talking about how they've really got to get up early tomorrow. Before they turn off the lights, they want you to make sure that you've picked up those free games they were offering, as the offer expires tomorrow.
If you haven't, just go to the PSN Store and open up the "Welcome Back" page from a button right near the top of the screen. That will let you choose your two PS3 (and PSP) games from the list. If you've waited this long, it's likely nothing they're offering has really thrilled you, but just in case you changed your mind, here's a heads up.
As for me, I already owned 4 1/2 out of 5 of the PS3 games, so I was obviously thrilled with their choices. I grabbed the Wipeout HD expansion I was missing and inFamous download to replace my disc. Maybe I'll finally play through that one as a bad guy now.
