Sure, but, to be fair, RSI has made decent work at polishing those angles. There’s still plenty wrong about the mechanics, and it’s buggy as hell too, but overall, I’d say I can immerse in SC in a way I cannot with any other game.
What kills SC in my opinion is not the “uncanny valley” feeling but rather the obvious greed and laziness of developers that essentially trapped themselves into profiting more off the unfinished game, thereby incentivizing themselves to stagnate. The game is very good as far as general gameplay is concerned - but the development incentives are screwed, and as a result, what could be a game of the century is now nothing but an empty promise or, at best, a sandbox.
