Just download some emulators and some roms for them, and you can play thousands of 80s-90s games all you want for free. You'll never have to worry about them turning into microtransaction crap, plus the gameplay is far better than anything current.
How is the gameplay far better than anything current ?
Genuine question tho, I just recently started playing again with portal and find most game to be boring, even the acclaimed one like cyberpunk and rdr2, but I don't see how Mario bros and likes could be remotely better.
current gameplay is optimized to be grindy to squeeze that sweet currency-ambra from the white whales(aka lonely people with money willing to pay for the adoration by the public aka ego boost prostitution )
