It’s the same picture.

Here you go

Yes it is the ratings on winehq, https://appdb.winehq.org/

And yes, an average user probably going to fire a game, figure out it is not working, and promptly go back to windows, which makes that data less accurate, but what can we do about it?

The left axis is total number of ratings of each type (Garbage, Bronze, Silver, Gold, Platinum) in a given month (not per app). For example for month 2016-07 there were

  "Garbage" => 22
  "Bronze" => 14
  "Silver" => 13
  "Gold" => 55
  "Platinum" => 61

On right side is the average rating. So if I assign values to each rating:

  "Garbage" => 1
  "Bronze" => 2
  "Silver" => 3
  "Gold" => 4
  "Platinum" => 5

I can get an average rating, which will be between 1 to 5.

((22*1) + (14*2) + (13*3) + (55*4) + (61*5)) / (22 + 14 + 13 + 55 + 61)
 ~=  3.721

Here is a trick that has been tried and tested over the years: Install another distro, and use that to install Arch. This way, you can rely on an already working linux distro till your Arch install works the way you want.
