I finished the overworld. If you take a look, you can see what I mean by "2.5" tiles when compared to other example quests 
EDIT: All caves, d-maps, shops, and pretty much everything for the overworld is now done. All enemies are placed too. Level 1 is also done. Check it out if you want, it's coming along. Now to finish up the dungeons. Lol, remember that time I made Z1 in like 18 hours? I sure don't.
My goal here is to make a replica of the first game that will be completely unpassworded and use/ have access to the new tiles in the new Classic included with 2.5.2. I will be making an 'authentic' 1st and 2nd quest in Classic, and Koten which means it will be a rule-for-rule remake of the NES game. There will be another version with updates, and changes that make it smoother (most of the NES fixes for example). These will hopefully help people learn, and see how stuff is set up in the first quest. Once that is all done, I will be working on my own '3rd quest' type thing, but the overworld will be modified too. Probably gonna make a project thread for it, since I'll need testers either tomorrow, or the day after. I plan on releasing the 1st and 2nd quest before my 3rd quest.
