There's lots of cheap indie games and game pass services on the consoles too, from what I understand. I'm not sure games on PC are much cheaper. Do you have examples of what you're talking about? Are big titles like $10 more on consoles for licensing fees or something?
I think there are three arguments to be made for PC being overall cheaper
1) XBox Gamepass offers a huge library of often new games for a cheap rate. That service is also available on Xbox consoles but those are much less popular than their competition.
2) Epic Games offers a bunch of games for free to entice people into switching over from steam, not sure about the current situation though.
3) Steam often offers very deep discounts on games and due to the relative ease you can buy keys from resellers you can get games for super cheap.
As an annectode I was able to get my girlfriend 250€ worth of expansions for sims for less than 40€, discounts this deep are hard to get on console.
Not at all. With sites like isthereanydeal.com and random and seasonal sales, I very rarely pay more than $25 for a game. My typical price for a game is $10 and one that I can play with all my friends inline would run about $15.
Grandparent wasn't talking about the games, they were talking about the systems. If you can find one, a PS5 or XSX cost about $500. You can't buy very much gaming computer for $500.
