As a strategic gamer who loves nonviolent competition, I appreciate OTC. As a copy editor and as someone who adores reading, I feel pain when I encounter so many errors in the otherwise-brilliant introduction to the game. I deeply want this game to succeed, and since it's in Early Access figured it was worth a shot at pointing out how much of an issue this is:

It starts with the tooltip you get hovering over the missions in Learn to Play: "Seneca Development will show how to profiting from the life support needs of the nearby Earth Colony," where it means "profit."

The intro has a couple of problems, but the really prominent one is "They require water to drink, food to eat, and oxygen to breath." The word here should be "breathe."

Then there are multiple its/it's errors, which I know really bother a lot of people. "The oxygen is rapidly cooled and stored in it's liquid form."

There are a bunch of pluralization problems, too, like "You can see how important the extraction of resources are" where it should be "is."

In some cases it's just the wrong word form being used. "You are now certified to plan and executive a successful business from Seneca Development." (I think they mean "by Seneca Development," too.)

Personally, wading through jarring breaks in the charismatic dialogue made it much, much harder to just enjoy the game. In addition to the above, there were general comma usage problems and a couple other odd disjointed bits. I heard you're in the middle of writing a new campaign, so hopefully you already have someone ready to do this kind of copy editing check. If not, though, let me know, and maybe we can work out something where I do a quick sweep through all the content.
