Doom 2 - Spent my childhood on dial up playing other friends over the modem. Up all hours of the night using chainsaws and rockets. Late 90s when Duke Nukem came out, It was the first game I drove immediately to the store and purchased. Back in the day when you bought the box and had to take it home and install it. Thought it was leading edge and funny as hell. To be fair it was at the time. Today that information is tracked. I'd like to know how many thousands of hours I spent on this game. But it was hilarious and late fun filled nights.
Today I buy 2-3 games per decade. But still game for a majority of my entertainment. One of the benefits of being an old gamer is that if you build a new system today it can play everything from the 70s to 2023 at a minimal. Toss in Emulation for other consoles in there you really have a plethora of choices, 4 decades worth to be specific. All of which contain no tracking, no always online, no micro-transactions. As gaming was intended! Really hard to find something that checks those boxes, about 2-3 titles per decade worth purchasing.
