Specifically considering all the DLC, peripherals, hardware, and other items—not necessarily for just one game, but used to play that game.

For me, it’s definitely DCS. I spent $250 on a used HOTAS setup, $400 on the Reverb G2, $1500 on my desktop PC, and $150 on content like the Supercarrier, F-14, and a few other modules.

I can take off from a carrier quite easily, but landing without crashing? Maybe once in every 20 tries.
