Can I Keep Him? Please!

Much to the dismay of my girlfriend I've decided that it's time to take in another stray. This time - a lonely Sega Dreamcast. I've never owned a Dreamcast - so it's about time I change that. I was reading Racketboy's post about shmups from a couple of weeks ago and I think that's going to be a good place to start playing. We'll see what kind of condition the system is in when it gets here. In related news, I've been eyeing Ebay a lot lately for consoles that I don't currently have. The thing is do I really need to buy myself another Genesis. Or another NES. I guess I'll just have to keep an eye on the Ebay, maybe I'll find a good deal...
