Zelda 2 The adventure of Link but I was too young (4) to do or remember anything meaningful about it from those playthroughs . So it would have to be The Granstream Saga. Then game got me back to RPG gaming. It was a short fun 3-D action RPG with a great concept for its story but with some terrible execution on that front. 

Dungeon Master on Amiga, around '88.

I had C64 before that, and though I've tried few RPGs, I just couldn't quite get into them - which is odd, since I've played D&D with friends.
Or maybe that's the very reason why I couldn't get into them at first - till this day, I find video game RPGs inferior to their pen&paper counterparts...perhaps, one day when AIs become sofisticated enough and hardware capable enough to handle them, I'll change my mind.

Dragon Warrior then Final Fantasy on NES. FF was such an improvement over DW since you didn't have to use a menu action to climb stairs!

This would hold true for the first 10 entries of the FF series. Dragon Warrior VII for PS1 must be the worst RPG I have ever played. The 105 hours I spent in it were some of most painfully boring Memories I have in gaming. The amount of grinding one had to do was beyond insane.

Final Fantasy I for NES

JRPG? Illusion of Time, also known as Illusion of Gaia

Western RPG? Tough to say. I think it was Baldurs Gate.

If it counts, probably Zelda II. Otherwise, maybe Dragon Warrior. Nintendo Power once ran a promotion where you got Dragon Warrior free (!) for subscribing, so that was nice. But then I fell in love with Final Fantasy, and I guess my avatar shows the result...

Adventure Atari 2600

final fantasy nes or dragon warrior nes 

Totally forgot about that! It's how I got my copy of the game too!

Chrono Trigger, I saw an employee playing FFVI in a rental store and he said it was one of the best games ever made and how RPGs had amazing stories and deep rich worlds, but I complained about the graphics of RPGs of the time and he said "If you care about graphics your should play chrono trigger", I rented that game and then got hooked on RPGs and when I returned to the game a month had passed or so and they showed me the first trailer for FFVII I was blown away.
