I'll never pay for mods unless they are as big as the base game. My issue is simply money vs amount of mods. I use so many of them and I'm not going to pay 90€ for the game and 5€ each for 1000 mods. (RimWorld I have even more than that. Skyrim about 700). You'd need to be insane to believe that paying this much is healthy. Of course someone who uses 3 mods will argue paying 20€ per month each, is fair.
A month? 2 bucks a month is still somewhere between 2 bucks and infinite bucks, depending on how long you use them, and that is not what seems fair for a mod. Remember when a whole game would cost a finite amount of money rather than a potentially infinite one?
I think my psn account is completely worth it. I play games daily and I always have something to play because of psn, from their monthly games and the library they have since I have premium.
And Netflix is also super worth it for me, it's running all day between me, my wife and kids.
