bushes shooting at you and killing you simulator
game that makes you realize that you won't last even an hour in a real war
fun if you have a party of friends with you
DLCs are crackable via DLC unlocker
many mods, I personally recommend Antistasi which is essentially rebel simulator where you steal ammo trucks, conduct ambushes, capture villages with population of 3 people and get shelled with white phosphorus and helicopter death squads
absolutely dogshit optimization, almost impossible to play without heavy modifications

This a great game, with an insane amount of replayability. I have played for 50 hours and only scratched the surface. I just got done with the main campaign but there is still loads left I could try. I have a lot more campaigns I could do, scenarios, challenges. That isn't even mentioning the workshop or multiplayer (which I still have yet to try). There is so much to this game. It does suffer in two majors areas though in my opinion. The first is performance, it's shit... (especially with mods). Second, the game doesn't do a very good job at teaching you things. There is a lot of detail and intricacies, which means that sometimes you will try to do something (like laser guide artillery using a drone) and it just... won't work. You will try everything to have it work, look at the in-game guide, look at the wiki and you just can't find a clear answer. Forums are vague and community guides are long-winded or non-existent. Despite this, it's a very good game once you get the hang of it. However, for the first 5-15 hours you will feel like you are just dying from nowhere until you get the hang of things and actually learn to use cover. A lot of the game is actually just about finding where the enemy is in the first place.
