First of all thanks the quick response,

Under content making I mean that you know in most of the games on holidays you can go to
christmas, easter etc. map where you can for example loot things and kill holidya/event related monsters and stuff.
I belive that there is a program or something that you can make models, textures and other things with.
But anyways thank you very much sir and I will probably post about the server when it will be in a test phase.
