I often tell this tale, but I couldn't fucking STAND Mass Effect until you get the Normandy and choose between Noveria, Theros, and uh...that other place (it's been years, sorry) The Eden Prime mission felt janky and like a bad introduction to the game's controls and mechanics. Just like "here, first ten seconds of planetary gameplay, here's a bunch of enemies, good luck, oh shit someone's dead, here's Ashley, better disarm these tiny bombs that look like cylinders and don't stand out at all hahahahahaha,"
And then the Citadel. Here, go find x in this gigantic twisting map with 7,000 entrances that all look the same while you grapple with character names, race names, and just what the fuck is happening!
But afterward, oh sweet Jesus. The game slows down and opens up, and you can finally take a breathe and find your footing. It's very much a game that assumes the player isn't an idiot, and assumes that Shepherd has been serving on this ship for awhile, so no lower ranking officer should be telling him how to run
After it all clicked, the Mass Effect trilogy became one of my favorite worlds in gaming.
