If nobody has mentioned it yet, stay clear of Valkyrie Profile and/or Suikoden II unless you are willing to pay between $100-200 per game, Suikoden being the pricier of the 2.
If you want something that you will pretty much only find on the PS1 and is well worth the system + game purchase price? Go with Vagrant Story.
I have yet to find a game, past or present that gives all that game did as well as include a great and memorable storyline and excellent soundtrack, specially the background sounds.
If you want Interactive Puzzle Solving, Great Stroyline to go with great Strategic RPG battle system, excellent weapon/armor creation system, etc... give it a go if that's your kind of thing.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
