visual novels work very well on even toasters because they are basically slide shows.
old adventure games are also a blast and work very well, look into lucas arts and sierra online catalogues. a great starter could be sam and max or grim fandango.
you could also try N64 emulation. there's a lot of good games on it and not demanding at all.
if you need something more sandboxy, rollercoaster tycoon and transport tycoon deluxe (or opentdd for the modern open source version, has multiplayer too with mod support) are great. apart from that, old civilization games and simcity are also great.
old real time strategies are also great. command and conquer series, stronghold series, age of empires 2, age of mythology, warcraft etc etc.
(help me folks im running out of genres)
basically either look into blasts from the past, or the indie scene. i recommend the former since although there's a lot of great stuff in the indie scene, it all kinda gets samey due to the same tools being used and the limited resources available pushes people into certain genres. you can't certainly beat the olden but golden ones on variety.
no way pezeshkian is talking to that clown lmao. this fucking country is a disappointment.
