I'm telling you, neither of these games is a standard first-person shooter. The war machine uses the third person, and the perspective is behind the characters, much like the third person over the shoulder perspective in Resident Evil 4, because many actions in the game (such as sticking to the wall and leaning against the bunker) are inconvenient under the first person. Radiation 3 also uses the third person, but you can switch to the first person at any time, which is very convenient.
In traditional first-person games, many people will feel dizzy and sick after playing for a long time. We call it 3D vertigo. Because of this, there are many over-the-shoulder games, such as Resident Evil 4 and War Machine. And shooting games are much more comfortable to play.
The war machine is a real man's game.
Radiation series is a classic of American RPG, with rich stories, high degree of freedom and extraordinary playability.
You chose two great games!
