I'm definitely enjoying the game. Can't really argue against buying it for 10 bucks if you like the Firaxis' XCOM games.
What I like:
-The new turn system. It did take me a little bit to get used to it, but I'm definitely liking it for what it is.
-Breaching is fun.
-I like the various characters' abilities that they have.
-Voice acting is generally good.
What I dislike:
-Everyone sounding the same. In War of the Chosen, the voice actors for the hybrid troopers clearly had some voice processing going on. But everyone in Chimera Squad sounds like a regular human being. I find it hard to believe that Sectoids, Mutons and Snake-people are going to be easy to understand while speaking English, much less sound completely human.
-It doesn't appear to be any potential ally factions in the city. I really liked the three factions in War of the Chosen, it would be cool if there were different political factions to try to sway to the cause.
-I will admit that the characters not being randomly generated destroys a lot of the personal imagination of your troops.
-It must be because I'm on Normal difficulty, but I find the rate of scarring of your troops to be really light, especially since in every mission I'm getting banged up pretty bad. In fact, in the last mission I kinda messed up and three of my squad went down and had to be stabilized. My last character also got pretty banged up, but only one person got any scar(my only one so far in the campaign, 5 missions in). If this was a campaign in XCOM 2, I probably wouldn't be able to field a viable squad with all the injuries that I'm sustaining from mission to mission.
Overall, I think it's worth it, and I'm looking forward to what the next proper full-fledged XCOM game will be.
