I've never seen so many people overanalyzing such a medicore series.
I can understand it. Mass Effect was pretty stunning when it first came out - as I said in another thread, it was from a time when gamers still believed that immersive games could become an art-form, and in many ways Mass Effect showed some of that promise, especially in the context of it being a s-f epic that dealt with many grand themes that had been floating around in s-f since forever. First time playing through, it felt like a proper
gesamtkunstwerk, with the added element that only games can have, of you being the character in the story, shaping it as you go (smoke and mirrors of course, but immersive enough to create a fine illusion, with gameplay that wasn't perfect, but good enough to sustain momentum). But really it was both the part-fulfillment of hopes and aspirations from the 80s and 90s, and at the same time the beginning of the decline, and it's been downhill all the way since then (not just the series, but games in general).
I'm playing through Legendary now. Third time playing through ME, second time through the others, and it now feels like an elegy, a slightly rickety but still captivating relic from bygone times, and the beginning of the poison that's killed gaming.
The reason we all worry it like a once-delicious but now cold meal is nostalgia for what could have been.
