I've been playing Divinity 2 for a while and there are some little things here and there that I would like changed for a better gaming experience. I was wandering if anyone would like to share their personal mods so that other people might benefit from it.
I'm not sure if there's all that much in the way of mods; I looked around and didn't find anything other than the sort of retextures you mentioned. I looked at modifying the game myself just to see if it was even possible but although dv2 unpackers exist, most of the data is stored in rather impenetrable NIF files and even those containing fairly straightforward 3D meshes seem very tricky to customise. Changing the game mechanics seems harder still. I hasten to add that I'm strictly an amateur when it comes to modding so just because I can't do it, it doesn't mean nobody can; but if it can be done, the methods for doing so eluded me.
I guess perhaps a request for Divinity 3 would be to release an Elder Scrolls-esque "Construction Set" type of thing so that fan made content was a possibility. The intellectual property issues in doing so can be a bit hairy, but I think it's the sort of thing that could help strengthen Divinity's position.
PS: If you're gonna upload your mod you should refrain from uploading it on this site for if you do that it will allow Larian.com to use it in any way they want without giving you any credit or royalty.
Even if they wished to do so (which I haven't seen much indication of) they can't just assume copyright (though "I am not a lawyer", etc); they may have rules about third parties not being able to sell derivative works, but original content will still be the property of its creator. Even where not enforceable, most places such as this tend to have some sort of code of conduct anyway so as not to alienate contributors.
