Call of Duty®: Modern Warfare® 2 (2009)

Yeah, we all definitely played this on 360/PS3 back in the day and had the time of our lives but how does it hold up on PC over 15 years later? On the single-player side, still pretty well: the campaign is fun, engaging, and well-varied in what it puts you through. I took on the challenge of making this my first Veteran difficulty playthrough (AFAIK, this entry is in the upper echelons of difficulty- nowhere near World At War, but still hardly a cake-walk) and had a fun-but-occasionally-frustrating time. "Takedown" will haunt your dreams for a while and you'll have one of two experiences with "Loose Ends" (the intro and ending will be a nightmare while the wave-defense section in the middle will be easy or vice-versa). Everything else is shockingly manageable once you've fully "immersed" yourself in the gameplay loop that's inherent with Veteran difficulty. Spec Ops is a bit of a chore and is the main wall for completionist types (3 achievements are outright impossible to get if you don't have a buddy to run the co-op missions with and some of the Veteran difficulty ops are unforgiving). Naturally, the multiplayer is also still a big draw and is definitely still a joy to play today. Just make sure you install something like ♥♥♥♥ before hopping online: the native multiplayer experience is full of hackers and cheaters while also possibly still being vulnerable to viruses/malware (There was a big rash of malware attacks a few years back that seems to have been addressed via security patches but, hey, you never know). ♥♥♥♥ and similar services patch up those vulnerabilities, give you the option of skipping all the leveling up if you just want to get right back to where you left off back in '09 (or you can grind through all those levels just like in the old days), and usually provide a few modded-in extra weapons and maps for you to enjoy. Just buy the game and replay it again for old times sake, you boomer. As an added bonus, Infinity Ward and Activision seem to not care about this title anymore, so it's usually running much cheaper than other older entries that they're still trying to squeeze some extra bucks out of. Much more likely to go on sale too IIRC.
