They still do that, Valve popularized the concepts of battle passes (with Dota 2) and loot boxes (with Team Fortress 2). They also took a paid game with TF2 and added all that monetization after the fact.
Counter-Strike especially has a pretty nasty gambling scene that Valve refuses to control, even though its only possible because of their marketplace and APIs.
The only real in-game purchase in Counter-Strike is the game itself to gain access to the ranking system. The skins are a superfluous add-on.
They knowingly profit from gamblers if you will but gamblers are going to gamble.
The gamblers were offered e-sport or gambling and they chose the latter.
You could use Robinhood to build up a growth portfolio starting from a handful of dollars or you could use it to buy 0DTE OTM options on credit. Guess which one the gamblers chose.
I’d like to point out that TF2 was part of the Orange Box bundle that included Half Life, Portal, and TF2. Those single player games were never given away for free, so as a purchaser of the bundle, I wasn’t miffed TF2 went free to play. In fact, quite the opposite. Because TF2 is free, there are like 50k people to play with me everyday. I think $0 is the right price for TF2.
I agree CS is icky re: skins and gambling. But to say “refuses to control” is disingenuous. They’ve done many things to curtail gambling, like preventing tourneys from displaying gambling sponsors and adding trade restrictions that hampered bot activity. Valve is between a rock and a hard place here- they recognize gambling is a net negative on the value of their game (hence the curtailing and remonetization efforts). Remember, valve didn’t create skin trading with the expectation of third party gambling, so this is something unprecedented they’ve had to figure out as they go. Despite its drawbacks, the gambling market has some positives that valve can’t ignore. It creates liquidity and demand for the skins. People who pay hundreds of dollars for skins hate to see their value plummet. So if valve nuked gambling today, it would upset a lot of folks. I think valve has done a phenomenal job balancing their business needs with the social obligations with the players.
