It's a meaner comparison that it sounds lol
It's more IMO Valve seems a bit lost in the weeds/dropping serious coin on things that might not pay off yet (that massive Linux focus hasn't paid off yet but could, in 5-10 years, heavy VR focus, etc), but forgot how to secure the bag in house, which was Blockbuster's doom. I think they're going to rev up in the next year or so, so it's definitely not 1/1.
I think if they wanted to nab Psyonix they definitely could've, and I'm gonna hazard a guess that Google and Epic out there creepin' on any studio that might wanna sell
