I think Crysis 3, released 19th of February 2013.

Crysis 3 is a 32-bit game.

I'm not sure which game would be the very first 64-bit only game and it depends a lot of where you draw the line. The first Titanfall, released in March 2014, only came with a 64-bit executable, and might very well be the first mainstream game to be 64-bit only (Call of Duty: Ghosts from November, 2013 predates it).

Before 2014, there were a few odd ducklings that were 64-bit only but they were typically insignificant indie games or student projects, such as e.g. Igneous from 2009, and 8-Bit Commando from 2011 which both seem to have been 64-bit only.

But 2014 was when the ball started rolling, and 64-bit only games started being released on a massive scale, for one very simple reason: Windows XP went end-of-life in April 8, 2014. You then had Wolfenstein: The New Order and Watch Dogs released in late May, both 64-bit only games, and that trend just continued throughout the year.

PCGW's backend data supports this as well, with a lot of pre-2014 multiplayer/live service games being listed as "64-bit only" nowadays as a result of receiving continuous updates throughout the years which eventually saw them dropping 32-bit support entirely.

Note that some of PCGW's data for random indie titles is most likely wrong, or have been affected by a later re-release on Steam. We list Cogs and Romopolis, both originally released in 2009, as being 64-bit only for example, but Cogs saw a 2025 re-release that dropped 32-bit support, while Romopolis was actually released on Steam in 2016 and so our data probably doesn't reflect the original 2009 release.

Looking into it a bit more, Call of Duty: Ghosts, released in November 2013, might actually be the first mainstream 64-bit only game.
