As much as I am keen on using Subversion, I quite frankly know very little about how to use it apart from the basics. Eventually I will need to setup a version control repository (Sourceforge sounds as good as any), but for now I want to get the very basic core established. I could really use advice on the feasibility of core concepts at this point before I delve too deeply into mechanics that can't be done, such as the Bloodmoon phases, spell systems, crafting custom magic items, etc. Since I am not well versed in code I need to know what my limitations are early on. Seeing Faerun, I am fairly confident that just about anything is possible; however, how easily can it be done is the better question. Is there anything about the presented concepts in the OP that seem difficult or improbable to achieve?
