Anybody else fondly remember the earlier Adventure Construction Set from the 1980s? It was similar, though more crude, software but for creating tile based adventure games. I remember breathlessly waiting for it to arrive in the mail one summer when I was a young teen, and then my brother and I spending countless hours creating games for each other to play.
There was also _Forgotten Realms: Unlimited Adventures_:

which I greatly enjoyed, and my NWN character, even got a cameo in one fan-made adventure.....
There was also STAC for the Atari ST - absolutely loved it. Unfortunately my artistic skills were not up to making anything good.
I loved that thing. I don't know how many hours I spent on that. I wish I could my kids interested in anything half as creative.
Yes! Until I saw the box cover illustration, I had totally forgotten that a high-school friend of mine and I worked months to build a Gauntlet clone on our 64K Apple ][+ machines due to the money it was costing us to play it at local game store/nerd magnet, "Dragon's Lair".
