I think you misinterpreted what was written. > "A lot of “casual” games end up using the hitscan method as it simplifies the learning curve for most beginner players. But what about games that aim to create an “immersive and realistic” shooting experience? They cannot achieve their goals within these constraints. We need to use an alternative method." It's not saying casual games are the only games to use hitscan but it's usually easier and quicker to implement hitscans than projectiles (and more intuitive for casual gamers). Half Life and Halo both use the hybrid system depending on the weapon, as written in the article.
