Ooh goldengran I had not heard of AG space! I have the original, Rio and Seasons, all of which I have completed, but couldn't find any others. I use an hp touch pad which does not seem to have as many apps as others as it has been discontinued. It might even be worth getting an ipad just for the extra games. I am definitely hooked - even more addictive than Gransnet!
I find AB toys and merchandise make good presents for GCs.There is a board game which has a real slingshot with building bricks and birds to make the targets. On eBay there are pages of items, some very cheap for stocking fillers etc. I am doing a pinata for Easter which will contain pens with catapult and bird tops, and torches.
