This is an impressive collection. I'm sure there are people out there with better, but I think this would be impressive by almost anyone's standards.
But, I have to agree with the people who say, maybe this is too much. I'm sure if you really just want a lot of games, and you don't care if they are any good, you can get tons of them. But, does anyone really intend to sit down and play through crappy games eventually just because they bought them?
I have about 200 games right now on 11 systems. I have half of my basement devoted to a video game space. Though there are some more stuff I want for it, I can really see one day space being an issue. Don't get me wrong, I love looking at my collection, and knowing that I could go 6 months + easily, and still game to my hearts content (and be enjoying every mintute of it). I also enjoy buying new games, and nothing beats the first time you pop a game in and start playing through it.
What I'm getting at though is, why would anyone need (or even want) something this large? I hate to sound cliche, but is this truely your life? You have to question how well adjusted someone is once there collection gets that big? Let's be honest, if you have 500 DVD's, you have a sweet collection? If you have 10,000 DVD's, you might have some issues.
