Grammar’s fine. Sentence structure in the third paragraph (the largest one) is a bit clumsy I guess. Maybe there’s a quibble about semantics in “you may also consider fully reformatting your operating system” - you reformat a drive and reinstall an OS. But grammar all seems fine IMO. I am a native speaker, I’ve certainly seen worse from my fellow countrymen.
Disagree. I bought Skyrim VR (even though I already had the non-VR version) only because mods exist which make the game worth playing in VR. Same for Fallout 4 VR - would not have bought that without mods.
