I would suggest figuring out what it was about each game that got you so excited, and try re-experience that. Choose one of the games on your list and go watch some trailers and read some reviews. I find I tend to stop playing games I love for long periods of time, but then I'll be at work and come across a trailer or gameplay video which instantly inspires me to want to play again. This has actually recently happened with 3 games I love but don't currently have time to play: Bad Company 2, StarCraft II and Shogun 2.
Also, try and forget about all the other games you have to play when you're playing one. The problem is that you're spoiled for choice. The same happens with me and music - if I buy 5 CDs and take them home, there is a good chance that I won't get into any of them, whereas if I were to have just bought one, the chances would be higher that I would end up really enjoying it.
It sounds like you're procrastinating because in your head you have made your pile of games a task which you must get out the way, instead of simple entertainment. That pressure is likely what's causing you to keep putting them off.
Also, you need to stop buying games man
