Need a better display method.

When it comes to systems, I think that the more you have the happier you will be. I would like to own them all and all the games but I know that it is not a dream that I can make a reality. We would simply run out of room for everything. Which is another problem of mine. I want to do the systems justice, by displaying them properly and proudly but when you live in an apartment, this is what you end up with...

You can't see all the awesome games or even some of the systems very well. Any one have an better ideas? We don't have much money so a new shelf is not really something that can happen. I know that would fix the problem and make everything look better but we just can't afford it. With this shelf, we can't even fit the Atari and all of those games and our other game systems on here. :( Sad really. 

How many game systems do you own and would you like to own them all? Also if you have an advice on how I can better display everything I am open to any advice I can get!
