Back-compat is usually a big deal for people, but I keep and use my systems for life. I still have a working PS3, and PS3 emulation has come a long way on PC, so I don't really need future Sony consoles to be able to run PS3 (or older) games. On the other hand, I did play a lot of PS1 games on PS3 even though I still have a working PS1 (sadly my PS2 no longer reads discs, and my PS3 doesn't run PS2 games), and I use PS1 emulation on PC. I have friends who got a PS5 because they skipped PS4, and PS5 allows them to cover PS4 as well. When my sister and her husband lost my original Xbox for years (finally got it back in recent months), XB1 came in handy for running original Xbox games. I do run DS games on my soft-modded 3DS, but I still have my DS Lite (in which I ran an R4 card). XBSX/XBSS having back-compat for all the previous generations of Xbox is pretty cool though. My issue is that not all my original Xbox games run on the newer Xboxes, and some of my X360 games don't work on XB1 or XBSX/XBSS. Also kinda sh1tty that for some X360 games that do work on newer Xboxes, their DLC does not. I used to run GCN games on Wii but I've gone back to using the GCN itself. Wii U will run Wii games but eh, I already got a soft-modded Wii. Wii U will also run GCN games if you soft-mod it. Anyways back-compat is cool, but it is less useful for lifelong gamers who still have the older systems, and access to console emulation on PC (or even on other systems).
