Actually, most of PC history agrees with me. Where do you think expansion packs originate from? Rise of the Triads? Stuff like Katakis?
Alright, stop saying this or provide receipts dude, because it's sounding like a lot of bs to me. Give me statistics proving the mods for money thing. I've been gaming since the sega genesis and downloading mods since I started pc gaming. Never before has payment been requested of me outside of a few fringe cases.
If this actually takes off and Valve/Developers make a ton of money off of modding, I wonder if a new business model might emerge?
Like, say a developer decided to make a "base game" and offers it for free, with mod tools included (although you could use your own tools if you wanted too). The idea is, the base game is offered for free and modders are the ones who develop for it. The original developers (and Valve) make their money through the Workshop cut.
Something like Free 2 Play with DLC or microtransactions - except instead of DLC or micros, it's community-built mods that are sold.
That's what I'm fully predicting is going to happen. Why pay employees for developing dlc if you can just get some dude sitting at home to do it for a pittance of the revenue made from it.
