Oddly I have given this a lot of thought, in the past month?and I was not reading these forums?my subconscious is plugged into this game :-)
Anyway, what I had concluded, based on ping factor and many other little issues, the PCs would have to be managed mostly by the server, in that they will be time delayed responses.
You attack X the PC runs to X and attacks him but you (the player) don?t choose the exact path. You are running and there is a ledge?depending on if you have a death wish or not?the character would keep on going or skid to a stop.
All in all these compromises allow for a freedom of space usage and scenario building not found in MMORPGs, but you lose total control of your character?it may even choose who to attack to get through to your target in the back of the crowd.
Further thought also means that characters could become restricted by faction/alignment?you may want to kill a particular NPC or your group may, but your character will not because of alignment, of course you should be able to over ride with a warning message?but this can really affect other things for your character, unlike now where some leeway must be allowed.
All this being said, I love this idea, I am not sure it fits our current goals though.
The trades are, control of actions Vs. freedom of environment and enforced role playing. Some might say it is an easy trade, but I have to say in the end I am on the fence?the more I think on it, the more I think it is a polarizing issue. Some will love it, others will hate it, few will be indifferent.
But I could have missed something or over analyzed it?who knows.
