A Bit of a Dilemma

My game collection seems to have grown a bit since coming to live in Austria. When we first came we bought two bookcase like units that I thought would house my collection and leave plenty of space for it to grow. Well......it seems to have grown alright.

My very full game units
As you can see from the picture there isn't a lot of space left. Tina said that once the units were full, that's it. Mmmmm, I've wiggled the games around to fit in what I have got and can't see anyway to make more space. Now that means, a) don't buy any more games or b) work on Tina to buy another unit. The first option is not an option, and the second option is not likely.......as I say A Bit of a Dilemma!!!
