What is it about Insurgency? So let me preface this with I love this game and I've been playing it a few hours a day basically for the last 3 months. However, it is not a very popular game. Under 15k players at its peak on steam. But I don't get why. Visually it's beautiful without being overtaxing on the CPU/GPU, the sounds are amazing (I damn near get a chubby every time I hear a Warthog fly overhead), and the gameplay/hit detection are some of the best in FPS in my opinion. My biggest gripe with the game is its movement, and it's mainly just the vaulting mechanics and the leaning.

Any ideas why this game hasn't achieved greater popularity? Is it just that ultra-realistic shooters are a niche game type?
