Donation button or humblebundle style 'pay what you want' with a minimum donation to keep from getting screwed over by transaction fees. (Say $0.50 USD for instance, which would result in about $.20 actually going to the modder if they're using a completely standard paypal account, or more if they establish themselves with Paypal as a business account.) However, this requires dedicated management of the community (which Nexus does well, Steam does not) in order to ensure nobody is scraping someones mod and reposting for profit. I'm a huge fan of the Humble Bundle system because it allows for reasonably priced mods (lets face it, most 'cool weapon mods' that every has 20 of are NOT worth $5 a piece) while still ensuring a modder can expect their efforts to be repaid to some level or another, depending on the quality and popularity of the mod, and those that want to give theirs away can still do so or funnel earnings towards charities they support. I dislike ads because they are ugly, bulky and most ad delivery systems are outright crap to have to deal with on a poor internet connection (I had awful DSL internet for years, and still don't have a stable 20/10 line when I'm not at university). The few places I have them enabled are Nexusmods, some YouTube channels I watch regularly, Twitch, and my university's student newspaper website. I would much rather give a modder $5 outright for a well-developed mod (I'm talking Project Nevada, WMX, Weapons of the New Millenia) and then give $1/$.50 for smaller stuff (pip boy retextures/remodel, for example, or a single weapon mod). But this has to come with the assurance of quality, which means someone has to do some detailed checking on each and every mod that hits the market, if you're going to expect money up front. Elsewise, publish the mod and do donations like they have for years. This may not quite be the place, but I'd like to add the potential discussion of whether 25% is a reasonable cut for the mod creators to receive given the support they receive in the Steam Workshop?
