Arcade games are what got me into emulation in the late 90s. I would occasionally search the web for ways to play pacman, until eventually I found a few arcade emulators. Then I found a group on irc and followed every new release of mame for several years. They had a release every week and you could count on at least one big hit added, usually a few. I was barely interested in other emulators until pretty much every arcade game I heard of was in game.
Now I have too many handheld. My current favorite is the Powkiddy RGB30, and I am waiting for the Miyoo Flip to come out.
If someone wants to try an updated version of the isometric Fallout games, check out Wasteland 2 and 3. Wasteland 3 has a lot less micromanaging inventory because there is no weight limit. The main difference in gameplay is you control a squad of 4 players instead of one, and you can hire a few NPCs along the way. It's a different backstory, but the environment is similar with remains of real cities in a post-apocalyptic future. They are all on Gamepass and there is a refreshed version of the 1988 original that can be played on an Xbox or PC if you don't like keyboards and mice.
