Well I wouldnt say it's really buggy, I only encountered 2 bugs in about 20+ hours of playing; once my OW didn't trigger, and the other time a building got destroyed where I had to do my VIP EVAC so I couldnt even get to the evac point O_o
Aside from that it's framy, I think it runs about 25 fps or some shit. But my PC cant run this game at all so im still glad to be playing it, the game itself is great.
I've only lost a few good soldiers, I'm playing on normal and its my first time going through XCOM 2.
If you really loved the XCOM EU/EW games then I would suggest picking this up for sure.
