1. Are you going to write up a how-to guide on the exported xml files and how to do things like add dialogue/quests/items/spells? I've done all of those and I wonder if something like that is planned. I know whatever I write can't be nearly as extensive as anything you make, having a lot more experience.
2. Are there any other neat releasable tools to add content to the game with? I'm sure you're well aware how much well-supported modding tools can add to a games community, having worked on many with them. Right now I can't seem to find a way to actually edit enemy spawns efficiently (I can think of one hack-y way to do it), but I know you're using unity which really wasn't meant for that. Another big modding hurdle is dialogue. Can you add lines purely through xml? Yeah if you hate your life. If the fabled obsidian dialogue tool can't be released maybe just some documentation on how things are laid out would be great.
3. Maybe most importantly, are you considering adding an overwrite folder (like Baldurs Gate / Witcher 3)? A folder you can add custom files to (icons textures etc) and have them able to be pulled into the xml. An overwrite folder would also allow you to edit the xml without actually touching your base xml data itself. Imagine if two people want to add weapons, if you both have to edit bb_items it's going to be madness trying to get things to work together.
I've probably put more time into messing with the xml files than playing the beta at this point, haha. I've asked these questions in other places but having them here makes the most sense, probably. I am so insanely hyped for poe2.
