Some unorganized comments:

-Try looking at the most helpful user reviews on Steam. Here's a fun game: drink a shot every time you load another page of reviews and do NOT see any red. Stop drinking once you see red--you win. If you can win the game without passing out... you've a far stronger gut than I.

-DOS is not the highest-rated (userscore) of all time on metacritic. Only the highest-rated new release (games released in last 90 days). It's still pretty high up there on the all-time list, but it's closer to being in the top 30 or 40.

-For kicks I checked out the handful of negative user reviews on metacritic. Most of them are people who literally only signed up to write a negative DOS review, and nothing else. The acts of spiteful competitors? Clearly, it's not the work of people who care about games.

-DOS' success seems to be coming purely from word-of-mouth. As far as I can tell, Larian has ZERO advertising budget. Hell, most of the big gaming sites haven't even reviewed the game (yet?), nor have most of the big youtube personalities. The big Wasteland, Torment and Eternity kickstarters may have demonstrated that countless gamers still want classic-style CRPGs.... but Original Sin has demonstrated that we still LOVE them.
