here is how big it is

It's "rough and ready", but it's certainly functional! A bit like the Jenga one I put together.

I just wonder how it will cope as you add expansions.

I was more interested to note that you were using 2nd Edition character (Cyborg) and that you had some other dice in the packet. I'd be interested to know what that's about...

I agree it is very rough. Eventually may stain and burn a design on it. But it serves it purpose. The next box will probably be much cleaner. I plan on making 2 more. I've been playing talisman since 1st edition so I'm working on adding my timescape to FF version (also the characters that may not make it into 4th edition).

Also the dice are extra so everyone has their own set to use. I wish they sold them separately.
