I honestly wouldn't even consider buying it. I understand that Xbox as a brand has been around for near 20 years now and that there is a large following. There is a large fanbase and that's great. People tend to have fond memories of what they grew up with.
The only thing I credit Xbox with is getting online infrastructure done well for consoles. That said, it was truly the Halo 2 player base that turned me off of Xbox initially. I had bought an Xbox OG with the Halo 2 Collectors Edition in order to play with my brother online. Unfortunately, he was never online. Once I beat the story, I went online and the user base was so horrible. I was always getting put on the team with 8 year olds that were singing into the mic and running in circles instead of capturing the damn flag. I also never knew how many lovers my mom had until I went online with Halo 2. I got so frustrated by the situation that I sold off the Xbox and everything that went with it after owning it for only a month. I never went back. Granted, subsequent systems gave different reasons not to buy them.
