I think for many of us, World of Warcraft was one of our first MMORPGs that we spent a significant amount of time playing. So the idea of having a place to remember characters you've left behind may be odd. But for lots of gamers they have a long history from games like Ultima Online and Everquest. And when gamers retire they don't quit gaming they just move on to the next game. With that in mind I found The Burial Grounds not weird but fitting.
It is a website that lets you create your own monument to a character you've played with a place for a few comments about your time in a that virtual world. It also lets you mention where you've moved on.
I remember thinking about (I'm sure I got the idea from someone's blog) how it would be neat if there was a quest you could do that actually killed off your character when it came time for you to quit. I don't know of any games that are like that. I've known of players logging out in their favorite spots one last time. Or returning to the starter area. So a site like Burial grounds isn't too far fetched. The graphics look like something out of original Everquest so the momunments themselves aren't anything to look at, but the idea that players don't want their characters forgotten even when they left a game on bad terms, one person typed "I vow to never play that game again" says something.
