Totally take some time off
Even think of turning over the reigns to someone or just co-operating with them for a while, if that would help. No sense in ruining what you've created for yourself
Your dedication to this project goes so far above and beyond what i've ever seen for any other game/mod :0
After making my LoTR conVersion for Age of Wonders: Shadow Magic I can't even touch that game, thats part of the reason why I ended up here.
I was partly drawn by this wonderful community that seems so reactive/proactive. Look at it this way, My LoTR ConVersion came with two Maps/Scenarios, the first, 'The War of the Ring' released in February which has 2300 downloads and counting (The most downloaded per day ratio of nearly any AoW map). At AoW there is a rating system its had 10 Reviews with a total score of 4.8/5 which is quite nice BUT it's also quite hollow, here it seems like almost everybody who's played the Mod has stopped by to congratulate you or offer suggestions. That's pretty solid
You've got a great bunch of people here who would probably willingly do some of the grunt work for you if you asked
I'm one of em, if you need anything just lemme know
