Team Fortress 2, CSGo, and Dota2 are among the most successful, most important, and very best games I've ever played and that have ever hit the market. You can shudder at the thoughts if you want to and that's fine if those aren't the kinds of games you like to play. But for me? I can't pretend that not having a story that I'd play once for a couple of dozen hours at best would have been my preference when I compare it to the literal thousands of hours I've spent watching and playing Dota 2, TF2, and CSGo. And imagine not thinking Dota 2 is a AAA game as they sponsor annual $30,000,000.00 tournaments.
There isn't a single sequel to any Valve franchise that I would trade my time and memories spent in Dota 2 for. Not a single fucking thing. Not any game that exists or ever existed, in fact.
Sorry you don't like the games that they like to make.
