A first-person sword fighting game? That has to be highly unpopular; it's nearly impossible to play those types of games without being able to see in third-person, jump around, and all that stuff. First-person shooters are -ok-, but still it's hard to figure exactly where to jump on a platform from, and see how far away you are from an enemy, etc.
EDIT: But at the same time, the "skills behind the keyboard thing" was used in RYL and RYL2, which I enjoyed a lot. I'd love to see it in PlaneShift, just not first-person
