Most of the free games are crap but they have on occasion given away absolute bangers (double- or even triple-A titles, although of course usually older titles or ones that didn’t sell well). I recently got The Outer Worlds: Spacer’s Choice for free (a game I wouldn’t otherwise have bought or even known about), and I ended up having a very solid ~55 hours of fun with it. I still do all my buying either on Steam or GOG because I don’t trust Epic and I hate their godforsaken launcher so I refuse to pay for anything that’ll be tethered to it, but getting a free game of that caliber certainly made up for the pain of installing it.
