I got this idea awhile ago when me and a few freinds were playing on a rp server,
the rp server dident have very strict rules for crafting and such and was more about roleplaying than setting limits on what you can and cant do without a spesific item like a stone crusher for cobblestone,
one of the things i made on the server was this small hotel, it was hidden from greifer underground and you could create your own room make and few changes to the hotel, this hotel quickly became hugely succesfull,
i think the reason is that it was an rp server and pepole were roleplaying, also it could be that the pepole there were just awesome, its gone now hotel got found and greifed you know the rest.
Anyways i was thinking of makeing my own rp server, much like the rp server described above, you can build things like stone crushers and gather things, or you can roleplay rather than collect and roleplay, the main reason i think this is a good idea is that it encourages things like working together on a project like a deffense tower, that being said i was wondering what everyone else thought about this idea, if you guys like it then ill probably set up a server, that or get someone else to host, my hosting computer is crap >.>
