I was just looking through one of my many "project" folders and thought I would share a tale with you about why you should think long and hard about an expansion before you set out to make it.
Back in June last year I visited Toys 'R' Us and saw a cool looking game based on the new Indian Jones film. The game was called Akator Temple Race Game and had a lovely plastic "tower" which represents a stairway of sorts and you turn the top of the tower and press it down and a couple of the steps randomly "collapse" causing players to fall.

"Brilliant" I thought. "That will make a cool tower for Talisman". So, I bought the game, even though it was about £20 and went home.
I got home, unboxed the game and found that the tower was the exact size of the Inner Region from the Talisman main board and the steps were just wide enough to take a Talisman miniature, so I began to formulate a plan.
I made an image file the size of the Inner Region, took examples of the art where it overlaps from the Middle Region (Black Knight's head, Port of Power etc) and set to. The board took shape and the idea was simple... Enter the Portal (probably using a Talisman), head through the randomly placed jungle (cards would be placed already) and then onto the Tower.

The Tower was my favourite part, as I could just imagine players going up the stairs, only to fall to and injure themselves by their own hand! It was genius... or so I thought.
Then I got to thinking about the mechanics. What is a South American Indian temple doing at the middle of the Talisman board? What makes this expansion different? What makes the encounter cards any different from standard cards or even the Inner Region spaces? Would a player be really annoyed if they got to the last step of the Tower and then fell and was out of the game?
I realise that one of my favourite cards from old Talisman, the Horrible Black Void, would do a similar thing, but this could happen to everyone who played the game. Not so much fun...
It then struck me that I did not have a clear idea of what to do with the expansion, or whether it would actually be a particulary good idea. All I really knew was that it had a really cool tower...
So, I scrapped the idea, gave the game to my girlfriend's son and then filed the images in a folder on my Desktop, so that it would haunt me to this day...
Oh well, at least I got a nice card back out of the game's box art. Now all I need is an expansion for it to go with...

The moral of this story, if it really has one, is that just because something sounds like a good idea, doesn't mean it will be in practice. I have been guilty in the past of making some cards based on a cool idea or a great film I have just seen, but you have to think about whether it will go with the game. The Princess Bride is an epic film, but it has nothing in common with Talisman. Most importantly, anything you make has to have a point.
This series of events hasn't stopped me from buying something that I think might make an awesome addition to the game, but it has made me think twice before I set to work on an idea...
