I finished game several times when I was a teenager in the early 90s. At the time, it was simply a milestone in the world of strategy games. I loved it so much for many years. The missions and the backstory are exciting. The game itself is dark, relentless, and unforgiving. The RNG factor is sometimes absurd. Compared to later versions of X-Com, the soldiers are more of a resource than characters you can form a connection with. They die quickly, and you order a new batch of soldiers just as quickly. It's still fun to play more than 30 years after its release and in my opinion it's by far the best game in the old X-Com series.
I bought this game on FLOPPY disk back in the mid-1990's to play on my Amiga A1200 back in the day... multiple disk swaps even with 2 floppy drives (I think it came on 6 or 7 disks... plus your save disk). It was awesome then, and it is JUST as awesome now... BUT... I can't get this to work on my Win11 PC at all... it just crashes or works briefly and dies... so... I actually play this on my Mint Linux desktop... in WINE... using the openxcom mods... which are awesome. The creators get a couple of bucks for a game they made more then 30 years ago.. and I get to use the modding community to enjoy this awesome masterpiece..
X-Com doesn't need any introduction, but you should install Open X-Com before attempting to play. Everything is confusing in this game and Open X-Com brings many QoL updates to UI. The simplest example would be: you build radars to detect UFOs, but there is nothing in the UI that shows the coverage of the radar. Open X-Com fixes many such details, and makes the game actually playable. For those brave enough I can only wish good luck...
