You need Landstalker, also.
Also, I'd say you will eventually have to pick up both Shining Force, Sin & Punishment and Shinobi III... they're all good games. So it's all a matter of what you feel like playing first. If you're up for a classic RPG with MANY hours of strategic battles and an interesting cast of characters, Shining Force is it. (Though the sequel is even better, and I bet it'll come out on the VC someday soon). But the other two are great too, especially Shinobi. But they (obviously) don't last as long.
Never played Ninja Spirit though.
