You simply must own Shadow of the Collosus, God of War and Disgaea. The metal gear games are excellent as well, if you like to be spooked the Silent Hill and Project Zero games are perfect. If you want to proof your 360 owning buddies that this little baby can still spit out decent graphics get Black and Project Snowstorm(this one turned out to be a very pleasant surprise, a fantastic actiongame set in the deus-ex universe, terrible story, fantastic action). Good choice on the ps2, the 360 still doesn't cut it.
