Most AAA games don’t, but a lot of games do. Sims 4 for example is still a very popular 3D game, but it’s not very demanding. MMO’s are often designed for very low minimum hardware.

False. Most games do target iGPUs, including most eSports and most indie games, which are the /most popular games.

The console AAA games are the ones that target proper GPUs because consoles have them. If they were targeting PC only, you wouldn't see them.
