Some of my fondest gaming memories are from this game. There was nothing ever quite like it, and the allegiance system created a special type of community bond that I haven’t seen repeated. At one point I had 10 “vassals” sworn to me, and in our allegiance that came with the expectation that you assist and mentor those under you. Stakes were higher when our allegiance committed to being red dot PKs on a white server…
MMOs are just so expensive to develop now that innovation is almost dead. You either make a WoW-like or you die (and many times you die anyway). They really don’t make MMOs like they used to.
I look at this differently. I think the extreme cost of an MMO should force innovation. Take the constraints for what they are and run with them. Accepting that you can't do it the "traditional" way is the first step to figuring out a better way.
There is nothing that says a high-quality WoW killer absolutely must cost 10 figures to produce.
