The Bard's Tale?
I first played it on my Commodore 64c. A friend of mine would get disks full of games from his uncle and we would just Load "$",8 our way through them. The Bard's Tale was one of those games and neither one of us had any clue what to do with it. I was only about 10 or 12 I believe.
I think I asked him to get a copy of the spells as well... somehow I ended up with one. You needed a listing of the spells for this game as they were not available as a list to choose from in game. Each time you wanted to cast, say, Mage Flame you needed to type in MAFL. Tedious by today's standards but business as usual then.
The game was essentially played out in a series of mazes. From Skara Brae (the city) to a series of dungeon locations like the sewers or mage tower. There was no in-game map so I resorted to the now-classic-but-then-required graph paper mapping of each dungeon.
This was the first RPG I ever played (and finished) and I absolutely loved it. There were many more that immediately followed (Wizardry IV, Magic Candle, Alternate Reality, Might and Magic...) but The Bard's Tale will always have the top spot for me.
Having said that I could never go back and play it.... I've tried. I grabbed a c64 emulator and fired up a game. It's really unforgiving. I know I have gotten soft with the games of today and all of the features we now have... but when you put together the fact that it is a tough game to get started with the "nostalgic" graphics and interface, as well as the fact that I have a golden memory to hold it up against... it will never be played again
