Rejoice fellow human!
Now scammy devs can't fool you with their "15quadrillion players play mah gam" bullshit, because this addon allows you to see exactly how many people played their shitty game. And that's of course on top of all the other useful additions, like quick sell. So yeah, a must-have for any frequent steam user.

amazing, makes steam so much better

Amazin extension if you use Steam. You can quickly see if a game sale is screwing you over by price history. Amazing stuff. Love it.

You will have to have spent over $5 on steam games for it to work

Very useful, works great. Thanks!
