I am making a game in the end time-scenario. But it is hard to find assets. Can I take the assets of "Fallout 1"? They are free available at www.spriters-resource.com
I would say no, spriters resource is game ripped assets that you don't technically have the rights to, it's fine for fangames or derivitave work, however it isn't ok to use for monetary gain or a jam like this.
