The best approach is to play games that respect their customers by having no microtransactions, or a fair monetization.
Most games that respect these criteria are indie games. The devs of those games deserve your money more than any AAA company, and their games are often just as fun as those you played when you were younger years ago.
I played CrossCode a few years ago, and it's been the most fun I've had in years. I don't know about arcade fighting games, but surely there must be an alternative.
