It looks like it's just an article but it's not! Anyway, this is one that I was following for a bit and then they made quite a few changes to their original intentions and to the development staff. I'm still interested so I signed up. Beta to start in early 2003.
i signed up over a year ago, dont hold your breath :(
Horizons looks pretty bland to me. It's not offering anything story or genre-wise that makes it stand out from the other MMORPGs on the market. MMORPGs seem to be falling into the same development methodology as pen-n-paper RPGs - you either have a great system with so-so setting, or great setting with so-so systems. Horizons looks to have a solid system in the works, but I need setting details!
