Do you remember Telengard? My buddies and I played Telengard so much.

@Ronnie yes! I had a route memorized that took me to something that gave out random gifts or monsters. Also did the thing where I would max out charisma and try to charm all the monsters. Lots of memories with that game. Loaded it from cassette into the C64.
@Eyes That’s a game one friend of mine and I would take turns and end up at 7am wondering where the night went. It was so fun.

@Ronnie What a great game. I played quite a bit of it later, around 1987 or so once I had discovered Ultima IV and RPG's.

I played hundreds of hours of this on the Commodore 64.

@Ronnie Yeah, staple of my TRS-80 gaming, somewhat later on my Atari. Hugely influential on young Mark's games, and somewhat even now.

Years later I find out it's a copy of a PLATO game, one of the first CRPGs.
