I agree with Lars, and I would add that the fact that base R3E is free probably means it is actually less affected by Steam reviews than other games. If someone has to pay an upfront fee before they can try a product out, then they're going to look at those reviews more closely. But if they have the opportunity to try the product themselves for free, and for as long as they like, they're more likely to see for themselves rather than relying on the opinions of others because they have nothing to lose.
