i admire your enthusiasm...the first two are doable and pretty straight forward.
Some MC manuals are already out(FR and Ravenloft), some can t be converted officially cause the setting is not officially out yet but i am sure some DMs out there have already done the work...hopefully they ll share their hard yakka when possible.
The last two require some serious work and hours of nearly free labour...unfortunately converting MC, powers, spells is even more time consuming than modules...
let s say in general converting is a grind...there s no PDF to FG converter available...everything has to be done manually.
it s getting better but still a grind and the financial reward is...very limited (my earnings only go into buying other converters' work basically). I personally do it for the community, so more people can have access to them.
never heard of it before...i ll have a look at it.
