You could always just wait. I'm only now working my way through the PS3 library and I could look up which games were considered the best on that platform, each title was ~$10 on average, that price often included a bunch of DLC, and every game is as patched as it's ever going to be. I'm playing Uncharted 3 right now which I picked up for $4. The box says that it includes $45 worth of DLC and on install it downloaded over 500MB of patches (which the internet tells me were very badly needed). I get all the fun and none of the frustration at a tiny fraction of the price
Once I run out of PS3 games I'll pick up a PS5 and work through the PS4 games that were actually worth it.
Once upon a time we got things called 'demo discs' with our gaming mags that had a taste of the games coming out soon so we could inform ourselves.
It's nice to see lately that Steam is providing more demos, which should have been a thing all along, but the logic that demos is bad (and how they disappeared largely some time ago) is only a benefit for those wanting to shovel crap out.
