Because who can afford a new gaming rig/system AND games to play on it?
I live in a developing country, I'm not either rich or poor and I have a decent gaming rig (i5-10400 and RX 6600)
For PC stuff you just need to know what to get and where would be the best place to get it (aka where is it cheaper) because here in Costa Rica (where I live) people will try to scam you into getting a 6600 XT for like $900 (US dollars, even though our currency is colones)
As for games you can either hop on the ship and sail or wait until the next major Steam sale. For games I'd recommend Steam but I feel MS Store/Xbox PC is fine as well
That reminds me of this. Some local store here tried to sell a 5700G and 3050 PC for 1941 dollars
