First of all... can I ask what you mean specifically by "old school style" RPGs? I think a lot of people might have different ideas of what that entails. For example, when you say that you used to play Bard's Tale, are you referring to the "old school" 1980's version that appeared on early PCs, or the rebooted PS2 version from about five years ago? KOTOR is definitely new generation action-RPG. DQ8 definitely has what I would consider to have "old-school RPG" game mechanics, albeit with an amazing graphical update.
So, I consider old-school RPGs to be those early console RPGs led by the DQ/DW and FF franchises. In this case, people have already mentioned the FFIV sequel on the Wii Virtual Console. Otherwise, I would look at games released for the PS1 that are playable on the PS2. Now you're looking at the whole slew of good RPGs, including FFV and FFVI on Final Fantasy Anthology, FFIV and Chrono Trigger on Final Fantasy Chronicles, DQ7, StarOcean (PS2 version was fantastic, IMO), Wild Arms, Saga Frontier... and a whole wackload of others that I am sure I'm forgetting.
