All the popular mass matket games work on iGPU: fortnite, roblox, mmos, arena shooters, battlen royales. Good chunk of cross platform console titles also work just fine.
You can play Cyberpunk or BG3 on damn Steam Deck. I wont call this low end.
Number of games that dont run to some extent without dGPU is limited to heavy AAA titles and niche PC only genres.
You can play doom the dark ages on steam deck. Granted at 30 fps, but it's still doom with ray tracing.
