The bulk of the mass effect trilogy was all about blowing s**t up, stabbing people with Omni-tools, and shooting anything within your cone of vision. If the cutscenes/dialogue wheel were the gravy, than combat was the meat and potatoes (or whatever else you have with gravy... ice cream?) Shepard and his/her 2 squad mates would take on wave after wave of enemies and come out virtually unscathed. Shepard, with his magical plot armour, would laugh in the face of highly trained, armed, and motivated battalions of enemies and cut through them like hot butter. He/She was a force to be reckoned with, and the galaxy trembled at their approach.
Wow, it's almost as if 'the player killing lots of enemies' describes literally just about every action game in existence? From shooters, to hack and slash, to space combat?
This is a very poor analysis.
All of these games involve the player mowing down groups of enemies for one very simple reason. Because it's fun. It's that simple. It's a video game, and video games are constructed to be fun.
I don't particularly like the narrative contrivance of every action video game protagonist being a superhuman who cuts through a thousand enemies. I don't particularly like the contrivances necessary to create a world full of psychotic bandits or mercenaries or whatnot that attempt to gun down the player on sight. But first and foremost, these products are games, and the foremost priority in a game must be entertainment,
