Congrats on the 300th map!
Game making is such a strenuous process... and the older we get, the harder it is. I'm always left with a sense of amusement when I think back on how much more motivation and time I had back in my teens and early twenties for this kind of thing. With that being said, I love game making so I could never really leave it. I'm thankful that, being an artist, I can still contribute to the development of an rpg without having to bear the full weight of all the responsibilities involved.
RPG Making is very often self indulgent, so hopefully you got back as much as you gave during the last four years. Maybe after Tristian is done... you could look into collab projects. As my Final Fantasy Discovery partner said... "two heads are better than one!" :)
