Clearly you haven't played the game, nor watched the Indy flicks closely enough. Drake actually DOESN'T like guns, comes up during the museum level (but its weird since he then uses them without a peep for the rest of the game to mow down entire legions of enemies), but depending on your play style fisticuffs come in quite a bit. Also Indy uses guns too. Watch Raiders of the lost arc again, when he is Cairo he shoots a half dozen guys, including the dual sword wielding guy in the crowd scene.
Of course there are gonna be some incidents when the rules change. What I was speaking of though was
in general. Indiana Jones uses his firearm at times, but those few moments are typically overshadowed by how he handles situations in the rest of the movie.
Ex. I don't remember him spraying those guys. I'm sure it happened in
Raider of the Lost Ark, but I can't recall it over the chase scenes, the interception of the Ark transport, the tiny uniform in nazi sub, and fisticuffs under airplane.
If it happened more often though, I would probably remember it like the dualsword gunshot (which was comical)
As for Drake, I admit I've never played the game
firsthand. But all the gameplay I've seen suggests shooting is a normal routine. (Its about gameplay choice like you said, but a lot of scenes make shooting the more reasonable conclusion)
