Does anyone know the name of this old computer game?

I used to play it when I was younger and cannot, for the life of me, remember what it is called. Each turn, you could only go a certain number of spaces. You traveled around collecting commodities. Then, you could start to build a castle. Within that castle, you could have mythical creatures. Then, you could attack other castles and try to overtake them. I'm sorry that isn't much to go on, but if you know what it is, it would help quite a bit. For some reason I keep thinking that that word "gold" is in the title, but perhaps not. Thanks for your time!
