I have only one in my games list. Killing Floor (original), 285.

I stand corrected, TF2 has 520. A game I no longer play.

A lot. And for at least some of those many of the achievements are no longer obtainable (example: Champions Online).

According to the site “steamhunters/games. com” (minus the space between “.” and “com,” I can’t vouch for the site so I won’t directly link it here) the game on Steam with the most achievements is called “Its Village” with 12,322 achievements.

As for my account, the game with the most achievements is Idle Champions of the Forgotten Realms with 724 achievements.

5000 achievements:

But dont support this dev - they copy-paste own games with little to no changes
