People are too used to how every other shooter works that anything they find different is immediately bad.
That's an awful defense for the game. Incidentally, the way in which
Mass Effect 1 differs from other shooters is that its mechanics are just bad. The controls aren't tight, the levels barely deserve to be called designed, the weapons felt very homogenous and shared the same flimsy feel, and enemies lacked tactical variety.
Managing overheating is easy if you know what you are doing, but shooting not the primary means of damage, especially with the more biotic or tech oriented classes. Combat in 2 and 3 is way more simplistic and repetitive, and the exact same rotations to take down barriers, armor, shields, life in awfully designed corridors. People are just to used to run/stop and pop shooting, but ME 1 is more about team composition, attacking in volleys (thanks pause) and managing individual cooldowns, something the shooters people are used to don't do.
Not really. I found that the most optimal strategy every single battle was to just spam every power you had and steam roll over your enemies. Team composition was irrelevant, and leveling them required little thought. It's not like any power choices you made lead to significantly different gameplay results. I'll grant you that levels weren't corridors, because they were worse: simply rooms connected by short hallways with rectangular bits strewn lazily about them.
ME 2-3 benefitted from more linear design because then the levels actually had a good sense of pacing to them.
The game had atmosphere and plot, but it's mediocre in nearly every mechanical category.
And writing wise, ME2 focused too much on character development (at the expense of a main stor) that of course comparatively character interactions and character-specific stories were better, but that doesn't make the characters themselves better. Or the writing. How many of those stories relied on the teammate having daddy issues to present conflict? Too many. Was Jacob more interesting than even Ashley or Kaidan in the first game because he got more lines and a specific mission? No he wasn't.
Tali and Garrus were far more interesting in the second game.
ME1 Tali was practically a glorified codex entry. But yeah, name the worst character in
ME2 to make your point, I'll be over here with Legion, Mordin, and Jack.
