I hope modders are given a choice though. I don't want to have paid mods only. It'd be nice to see free and premium versions of mods though. "If you pay 5 [currency here], you get an added bonus of a new town to explore, with new quests, items and characters. Along with the added feature of being able to hire henchmen to order about in all mod-added towns!" Paid users would also get priority technical support, obviously.
That's something I'd accept. I'm already hurt by having to pay for tons of DLCs (which is why I wait for a discounted GotY), I don't want to have to pay for mods as well, even though quite a few modders deserve it. I'm a student, I don't have a stable income or budget yet, so I'd prefer not to spend money for every little thing. If I had an income, then yeah, I'm sure I could designate a part of it for game purposes (including donations), but that's not true right now.
Console paid mods might be brought in though. Unfortunately, since they have no history of having mods for free, it seems easy enough to force it on them. Especially if it's some sort of extra work to port from PC to Console (even if it's minor). Still, I'd prefer the Basic Version vs Paid Version thing.
All-in-all, I'm okay with having paid mods, really, so long as it's the modders' choice to go with paid or not.
