every single person that has replied to this thread would have loved UO back in the day, you could make everything or do anything that has been mentioned here so far (except for the seige stuff)
I have always wanted to be able to create barding and such for my mounts so that would be cool imo.
I am really into the idea of the RTS city building stuff in this realm. The seige equipment as mentioned earlier would be a very cool thing to be able to build and hopefully use in game to me as well. Could you just imagine having the ability to create such equipment and war with anothers city, beseiging it and having war with each other? That would be neat. Or possibly being able to actively have war with mob encampments of some sort?
Could you imagine how cool it would be to see a mob encampment and with the help of a few player ran communities be able to create seige weaponry and then lay seige as a group to the mob encampment? Talk about player created content! Wow that would be cool.
And lest we even go into how totally cool it would be for crafters to be able to create cannons and such to add to your ships to upgrade them for sea warfare? How cool would all that be as well.....
