Depends upon what you pay - certainly the second market will see a surge and drop in prices. If you can tech on top end 5 years later, it's not that bad and sure wallet friendly.
Also factor in that it usually takes a few years until the full potential of a platform it tapped, so the PS4 in it's prime days for games.
I do not understand your argument as the parent post is saying the PS5 can play PS4 games. So the PS5 will also benefit from the great games coming on PS4. The prices of the games would be the same, you would benefit from the same experience of the devs developing on the PS4. The only disadvantage is that the PS5 will be pricer. And it will also be less ecological-friendly if you intend to buy an used PS4. But that's it.
I've seen a few people who ride one generation back and buy used. It means you can get the console incredibly cheap (and can choose the best/most reliable variant), have a huge catalogue of games to explore (which are also incredibly cheap), and already know which games are standout and which are misses. Doesn't work if you're into the latest multiplayer games though.
Should be, at the end of the day they are both just X86_64 systems. It isn't like the console generations of old where each one would used a specialized CPU usually designed specifically for that console. (The PS3 had to include a full PS2 chip for its compatibility layer)
All that said, I do see them somehow screwing it up.
But it doesn't have any games worth playing on it, whereas the ps4 has an established and extensive library that would take (me, at least) quite some time to get through. Probably long enough for the ps5 to become more purchasable than a steel Daytona, unlike now where it"s apparently extremely difficult to buy
For me, I'll get a PS5 for Demons' Souls alone. When you factor in upcoming games like the new Horizon Zero Dawn next year and the graphics-upgrades like Cyberpunk 2077, its definitely worth it.
Although, realistically, it'll be a few months into next year before I actually get one.
Worst case, creditors cant take experiences from you, nor would they bother with most consumer goods.
I’m wanting to stay eligible for low rate mortgages or leases, and thats the priority but yolo. More motivation to make more before it becomes a problem, the end.
