From the list of what you have...Final Fantasy III followed by Chrono Trigger for RPGs. For the Genesis, those are all fairly weak games. PS3 is the weakest of the series. It's ok, but not on the level of FF3 and CT.

There IS a big difference between action and turn based. IMO Light Crusader isn't really an RPG, nor is Zelda. They're more adventure games. If you prefer that to menus, go find Landstalker like someone said...you'll love it. or Wonder Boy in Monster World (both for Genesis). There's a lot of that kind of stuff that's very good...most people don't classify em as RPGs though.

If you are gonna start traditional RPGs though...start with FF3. AMAZING story...fairly linear, solid gameplay, not too complex. Easily my favorite game of all time, hands down.
