A site like Reddit could be run on a skeleton crew of 20-50 people. That's what Elon Musk is trying to do somewhat with Twitter, slashing unnecessary employees.
Look at it from the viewpoint of an executive. "I managed a 5 person team." makes you sound like a loser. "I managed a 100 person division" makes you sound like a Big Important Person, even if 95 of those jobs were unnecessary.
Also look at it from the viewpoint of investors. If an investor puts $200M into Reddit, they want Reddit to be spending $100M-$200M on growth. No investor would put $200M into reddit if reddit was going to just run a barebones operation spending $20M per year and then coasting for 10 years off the investment money.
Simplest is Retroarch or Daijisho.
If you really want to get fancy, consider getting one of the cheap handhelds with build-in game controllers, like an Anbernic RG353 or Retroid Pocket.
