I consider myself quite experienced when it comes to "role playing games" on the computer. I mean, I've been around. But I'm always looking for something I haven't already tried. Obviously, I'm looking for quality, but quality can be many things. Gameplay is most important.
If there's any of you who have good suggestions for old RPGs (I'm talking at the very least before Baldur's Gate era), I want to hear them! Just not "action RPGs", please... Anything that smacks of Diablo will get smacked right back!

To give you an idea of where I'm coming from, some of my old favorites include (and could be inspiration for you?):
The SSI AD&D "Gold Box" games (Pool of Radiance, Curse of the Azure Bonds, etc. Champions of Krynn, etc. Buck Rogers, Savage Frontier series, Eye of the Beholder...)
The great "brand name" series: Might & Magic, Wizardry, Ultima, Phantasie
Great single titles such as Bloodnet, Superhero League of Hoboken, Albion, Betrayal at Krondor, Wasteland
More obscure games in the vein of Aethra's Chronicles, Dark Designs, The Legacy...
You see where I'm coming from? You nod your head at several of those titles? Well, bring me more!

(The first person to suggest Fallout does not get a cookie, by the way)
