If you are dumb like me, this game is a lot. Having played XCOM: Enemy Unknown, I thought I was prepared to just jump right into XCOM 2: War of the Chosen. While the core gameplay is the same between both titles, XCOM 2 and WotC add a lot of new aspects to gameplay and changes many things familiar from XCOM: EU; most notably, the strategy layer of the game.
The strategy layer of the game is probably what gave me the most grief starting off; not that I realized it at first. It wasn't until twenty hours into my first playthrough that I realized I had been wasting too much time scanning unnecessary targets and mismanaging my Avenger. Suddenly conflicts started feeling unwinnable and I was losing soldiers left and right. Eventually, I had to do a full restart of my campaign. Again, I am very dumb.
For players coming to XCOM 2 straight from XCOM: EU, I would advise a bit of caution jumping into WotC completely cold. It may not be a bad idea to take some time to get acquainted with the GeoScape and facility management of the Avenger before starting properly. For me, it took a failed campaign and playing through the entire Tactical Legacy Pack to really get a good handle for the game. But once I did, and started my second campaign properly, it went far smoother, and I had a hell of a time.
Once you get past the learning curve of XCOM 2, it is a very deep and varied game with lots of possibilities. I feel that the story of XCOM transitioning between a government organization to a rebel faction fighting against a world overrun by aliens is a fantastic and unexpected twist on the story that changes the setting in lots of interesting way. In general, XCOM is great at having unique and interesting lore, while leaving enough vague and flexible enough to fill in the blanks yourself, allowing each player room to create their own narrative and emergent story; a property of the story that fits perfectly with custom soldier creation.
I get the sense that The Chosens are generally seen as an intrusive burden on the game, but at least for a first playthrough, I think they add a remarkable amount of drama and tension to the game. I find their sudden interruptions and long monologues endearing, not unlike a reoccurring cartoon villain; though on subsequent playthroughs I can seem them getting very old. Aside from The Chosens themselves, the game has decent pacing, with interesting unlocks and story beats that drive you to continue forward. The game suffers the same progression issues as XCOM: EU, in that it generally starts out difficult and gets progressively easier, until the game begins to drag by the end, just waiting to be done as you steamroll the enemy.
Overall, XCOM 2 is a fantastic game, while is suffers the same issues as its predecessor, is adds and expands on it in incredible ways. I've never been a fan of tactical games, but I will absolutely make an exception for XCOM. If you generally enjoy management and strategy, and especially if you enjoy tropey sci-fi themes, you'll probably love this game.
