I actually never played inFamous. It was always on my "to buy" list, but a lot of things were placed above it in priority, and it just kinda phased out of my memory. I'm glad i actually get it for free, now. So, that and StarDust HD will be mine.
Also, i HIGHLY recommend Wipeout HD. I purchased it when it first came out, and it's probably the best thing i've bought from the PsN. Well worth full price, so getting it for free is awesome.
I was never that sad about the PsN downtime, considering i mainly use my xbox, but it is nice to know that i'll be spending a decent amount of time in the near future getting back to my sony roots (Ps2 fanboy for life).
