So you don't have a source at all then. Just as I thought.Based on basic bell curve concept. There will always be a certain percentage of outliers on either end of the curve. I don't need a source for basic math concepts. My estimate of 4% complainers is actually unrealistically large. Consider yourself special.
Literally? Thousands? Maybe you have a source for that.
As far as my source is concerned, feel free to look at the steam reviews. They are all easily accessible.
Honestly, even the positive reviews are a fairly scathing critique of the engineering system. Does anyone say they actually like it? Best case is people saying that they tolerate it, but that doesn't mean something should be preserved!
