I would like to propose the reinstatement of the warptex system.
For those who are unaware, the warptex was a system where you could create a level in offline editor, and get it uploaded to your 'world'. This was essentially a playerhouse system of Classic. Allow me to first address that this would not replace the idea of having houses on the overworld, this would be in addition to having houses and/or guild houses on the overworld. I believe that if players want to, that they should be able to create their own little world inside of their house.
The first problem we would encounter would be: How will we go about uploading the levels?
We could either continue the system of using offline editor, then submitting your level to a staff member to have it uploaded continue, or we could implement an online editor. The reason that i lean more towards implementing an online editor is because due to the possibility of Classic going Facebook, newer players would have to download the Graal client in order to download the offline editor which seems like a bit of a hassle and maybe just a bit too much for us to ask of newer players just to design their house. An online editor would be quick and easy.
The second problem, branching off of the online editor, would be: How do we regulate what people are doing with the online editor tool?
If/When Classic goes Facebook, we cannot be certain what our playercount will be. Whether or not we will be able to manually manage each individual person's warptex world is uncertain. Two ways that we can attempt to manage warptex playerworlds and the use of online editor, would be to, 1.) Use a soft threat. By that i mean, if you are caught creating vulgar images out of tiles, or using online editor that in any way that it is not designed for, then your house could be deleted. The other way we could manage this is 2.) Have a form of babysitting where we might have a specific staff position created to check playerhouses bi-weekly or so.
Any other suggestions regarding this are welcomed. I just wanted to humbly throw the suggestion out there.
