^You either 'get it' or you don't. It's alot more tactical and slow compared to 99% of other online shooters, and has that stealthy element about it.
Its also got a really high learning curve, I remember when I started out I was constantly being utterly destroyed. After I got the hang of it there was few people I couldn't beat. The customization in it is also great.
Btw, the golden rule in MGO is 'headshots.' If you get 1000 Kills on MGO, at least 600 of them should be headshots
