It's hard for me to make a vote on the second question. Depending on how capable this feature is, I could see myself paying anywhere from 10 to 20 dollars. If I can make something like this or something like this then it is for sure worth 20 bucks. If it's purely for making square dungeons, we already have a free plugin for that here https://forums.rpgmakerweb.com/index.php?threads/mbs-fple-mv.57363/ So there would need to be plenty of nifty features. For now I can't make a vote until I know what features this tool or what not would have. I don't care for a tool that would only allow for what can already be done for free. It would need to be pretty capable.. what ever it may be. Making a town with simple geometry would be nice.. Being able to do more than just straight tunnels would be nice as well. Being able to have objects like book shelves tables and more would be a must as well. Maybe simple 3D objects like pillars... maybe room shapes that are not just square. You really gotta be able to bring something special to the table if you want my money.
