I'd love to see some Atlus games remastered, but it seems that they will be getting a PSN release instead (like Persona 3 FES), which is fine. I think a disc based re-release is better, but getting them by any means is fine.
Actually, I would be interested in a Killzone collection.
I think that is one that Sony could easily do as well. I mean KZ is a Sony IP is it not?
KZ1,2, & 3 in a bundle for 40 - 50 bucks. That would be an easy sell for me. 3 games for the price of one.
