This is it. The game. There is no "genre" for TBS. There is also no base-building genre. No, this is the only game of those genres in existence. Don't look it up; just trust me, and throw all your money at the screen in the name of Julian Gollop.
XCOM: UFO Defense (UFO: Enemy Unknown in the EU... I see what you did there) is, as I mentioned, THE turn based strategy game. It's suffered from aging mechanics and the limited capabilities of early Windows and late DOS platforms (as well as a few bugs and a rushed ending), but other than that has remained intact only because few have attempted to replicate it, and even fewer have succeeded.
This is NOT going to be an easy game to play. Let me just get that out of the way. Your troops WILL die. You will ♥♥♥♥ up. And that's okay; that's XCOM. Unlike XCOM 2012, there's no dicerolling, no RNG hitscan. Every bullet is precisely calculated to do damage to the target it hits-- with that meaning you.
In this title, there is no shame in going through the first pages of the manual your disc came with-- what, no disc? Don't worry, it's nicely packed in PDF form if you go to the game's steamapps files. The game itself offers no handholding across the street, and you'll have to watch it closely to make sure it doesn't throw you under a bus.
Play on Beginner if you need to, Challenging if you have the nerve, any higher and you shouldn't cry when your inevitable loss comes around-- you earned it yourself. And that pretty much sums up this game.
Unlike 2012's reboot, everything you do in this game is done by you. You have more control over XCOM and more in-depth micromanagement of your arsenal and supplies. You won't have to pick one out of multiple simultaneous missions (unless you let your interceptor hangars get outdated, you have a constant view of the whole world, you can have multiple skyrangers, and you can establish multiple bases. Micromanage your arsenal and supplies, build the square 6x6 grid that is your base, and kiss the ♥♥♥ of the council enough to survive.
It's a no-brainer whether the average strategy gamer will want this or not-- give it a shot, you'll probably like it once you figure out what the shiny red and green interface buttons and knobs do. The question is...
-Will you buy it alone, or do you like suffering enough to continue on to Terror from the Deep and the legendary Crawler Carrier missions?
-Maybe you'll continue even farther (or be rational and skip TftD), and defend a smaller-scale urban area from an alien assault in XCOM Apocalypse?
-Or maybe you'll just buy the $15 XCOM Complete Pack and play through all three strategy games, a space-combat/base management hybrid in SPACE, and... some ♥♥♥♥♥♥ Unreal Engine 1 game we all deny the existence of!
In other words, despite all the bugs, poorly aged mechanics, and clunky DOS interface, plus the use of DOSBOX, I absolutely recommend this game with an 8/10 (9/10 if it weren't a messy DOSBOX port). With OpenXCom, go on and raise that ♥♥♥♥ to 10! TEN! OUT OF 9.9, A 10!

Mod Showcase: OpenXCom
A complete overhaul of the original game that fixes some of the clunky interface and removes the need for DOSBOX, plus gives us resolution options and optional improvements such as tweaked bulletcam and better sprites, as well as mutators. Definitely worth checking out, since the changes to AI behavior it makes are optional.
Recommended Purchase Method: XCOM Complete Pack
