It just feels right having that weighted block of inputs in your hand when stumbling through them, but it's not exactly necessary. Third-person shooters lend themselves to joy-sticks and bumpers. Cue the Legendary Edition with its most underrated new feature - controller support. It's an intriguing oversight, and one that I couldn't seem to find a fix to circumnavigate, and so I was strapped to mouse and keyboard.
The game, clearly designed for controllers, didn't support them. All of the Mass Effect games are already available on PC, and that meant that it was incredibly easy to get into the classic trilogy even prior to the Legendary Edition, but there was one slight hurdle.
