Some Drawbacks with idStudio

idStudio itself is ~60 GBytes

Individual map asset packs are 5-10 GBytes

You will need to login to your Bethesda account to access/publish mods

You need a fairly powerful PC to optimally run idStudio (32 GBytes of RAM is recommended)

idStudio may take a some time to do the following - Boot up - Open a map - Load into a map - Package a .map file (packaging decls, strings, textures, & audio will only take a few seconds)

Packaged map files can range from 500 MByes to 2 GBytes in size depending on how large the maps are
