You and the GF should try the demo for LBP. It's a lot of fun in local MP. I bought two wired controllers on Woot for $5 each so we have 4 controllers.
I have Resistance, and I just can't seem to get into it. I bought this controller, which helps...

But sometimes you can't change shoot to the "actual" triggers... you're stuck with the "bumpers". Which is the case for the Uncharted games. They're decent, and worth playing. Nothing I would have bought the console for, but as long as you have it.
Probably the best exclusive to me was inFamous. Maybe not your type of game (maybe it is) but I liked it.
Let us know if you keep it.
EDIT: Best part is that when the PSN store comes back online, you might be eligible to get 2 free games. 2 of which are LBP and inFamous.
