although, if i were to give some low spec games to suggest for a laptop or whatever:
doom (chocolate doom, crispy doom, dsda doom are great source ports for the originals. my suggestion is dsda doom, but if you need some extra fps then use crispy doom)
mugen (or ikeman go, both are equally as good as one another.)
morrowind (amazing roleplaying game for a cheap price!? satisfactory.)
skyrim (special edition needs more fps, but both can be pretty much modded into oblivion which also includes modding the shit out of the game until optimization is increased by 1000%. can basically run on anything as a result.)
super mario bros x (both are really good emulatorless mario games)
the escapists (pretty good puzzle game for a really low spec price)
thief simulator (this game runs like shit regardless of what you run it on lmao my rtx 3060 is a gtx 720 with this game. regardless though, it's some really good indie development fun and i suggest it!)
wadanohara (play it. play it now. when the playing is a requirement.)
