"Games that don't necessitate a dedicated video card but have tons of depth. I love games like this, as they can provide hundreds of hours of gamplay without needing even a moderately powered PC."
As someone who is stuck with an oldish laptop (Though GPU included, yay!) for years because university and lack of money, I absolutely endorse this direction of curation. There are literally hundreds if not thousands of great games - including DOS-era retro - that are pretty easy to run, yet has content and quality for days ^^

Thank you!
