The impending release/announcement of the PS4 got me thinking; there are a lot of PS2 games that are about to get very rare, and very expensive - just as the PS1 and N64 libraries became rare and expensive when the PS3 arrived.

Last-gen is old. Two gens ago? Classic.

Which is why returning to my PS2 backlog - those gems I never got around to playing - is more important than ever. I wrote this editorial on the frontpage, and I'd like the community to join the conversation.

For those too lazy to click, my five picks were: Dark Cloud, Digital Devil Saga, Rogue Galaxy, Dragon Quest VIII, and Xenosaga.

Let's share some PS2 memories; what games do you regret not playing?
