What do you guys think?

Great list of games. Especially OKAMI.

I think you will have lots of  fond memories of the ps2.

:D

I would say that you should pick up Okami and Metal Gear Solid 3: Subsistence.

Pick the others up later when you get more cash....it's not like they're going anywhere....maybe with the exception of Okami, it didn't sell terribly well (despite being a brilliant game) and it's print run was not huge.
