Probably controversial but half life 2 for me. I got it very cheap on a sale after years of hearing how good it was. Just couldn't get into it. Even worse, every time I felt nauseated after a couple of minutes.
I guess this is just an example of a "you had to be there" scenarios. I was there as a gamer at the time but had no funds to play all the games. I skipped on HL 2 and can't get into it 20 years later.
Worst advice. ChatGPT is not meant for this and can doore harm than good.
