Decades ago, I saw Panzer Dragoon Saga, Shining Force III, and Magic Knight Rayearth all at Electronics Boutique and only had enough money for two. I picked up Shining Force III (amazing game) and chose MKR over PDS because I knew MKR was the last saturn game and I figured it would eventually be rarer and more sought after.
Well, I hated MKR, and refused to pay crazy prices for Saga after passing it up. Years and years fly by, and one day I'm at a garage sale and see a woman selling a bunch of very rare saturn games for dirt cheap in a box. She clearly had no idea what she was selling. There was no panzer dragoon saga, but there were copies of Burning Rangers, Shining Force III, Sega Ages, etc. all in mint condition, which I bought for a paltry sum (like under $50). I already owned all those games already, but I managed to turn those games into a straight up trade for a sealed copy of PDS on a gaming forum.
This was only like 3 or 4 years ago. All my praise for Panzer Dragoon Saga is not nostalgia, nor is it because I payed out the ass for it. It's legitimately a terrific game. I wish I could play it again with new eyes. One of the best gaming experiences I've ever had. To lust after a game for over a decade, and then to get it and have it live up to the hype is something else.
Enjoy your playthrough of the game. It's a master piece as far as I'm concerned. Possibly Sega's greatest hour.
