A lot of science fiction literature makes use of concepts that cannot be appropriately described in the vocabulary of the present, and demands an inductive approach; just go along with it, and it will become more or less clear as the story progresses. Accelerate is bordering on linguistic overload in this sense. Add to that a horde of strange metaphors and you have an “enormous piece of extravagantly confusing art”, to use a quote embedded in the work itself.
While it was occasionally hard to understand the protagonist or the context in a given situation, the story is actually relatively clear: you become indoctrinated into a cult of religious terrorists and attempt to bring forth some kind of revolution. In this, you have no agency. Perhaps you have no choice.
Regarding it as a gesamtkunstwerk, my feelings are varied. Its strongest point is definitely the writing; Accelerate reads like a modern sci-fi classic, only more poetic, though I would have had an easier time accepting it if I had sensed more coherence between the different contexts. As it is, I often felt I found myself in a new situation, not understanding how I got there, which also compromised the connection between the player and the protagonist. The visual presentation was the most lacking element of Accelerate. With a plain interface and simple animations, it brought thoughts of the 1990’s, rather than of the future. The music, on the other hand, was nice and appropriate; most of it I would describe as cyberpunk muzak, although at times it became uncomfortably brutal.
