One of the things that I love about Massively Overpowered's readership is how fans often bring games to my attention that I never knew even existed. This is particularly true in the case of older MMOs that died in early development.
Last week in the comments, reader Celestial linked to a trailer of Highlander Online, which has to be the very first time I heard of this game. A Highlander MMO? I thought that was just a thought exercise that players like to bandy about from time to time: "Wouldn't a Highlander online game be cool? How would it work?"
But believe it or not, one was actually in the making for a while. While it obviously never released, Highlander Online deserves a bit of investigation to see how far it came and what it was aiming for in its design.
