First off you should know that everything you see in an EvE gameplay video looks roughly 9000x cooler than it does in real life.
The video you've just seen above is in regard to a war that's a-brewin between some 50,000 players in the EvE universe in the star system of Delve. I'm not going to go into details but just know that if you're an EvE pilot you should stay the fuck away from Delve or any surrounding systems unless you want to spend the rest of your days in a pod.
Don't believe me? EvE is serious business, some guy even wrote a song about it.
Want even more proof of the seriousity? PC Gamer will be reporting live from the battlefields of Delve - as if it were a real place!
As a casual EvE player (yes, we exist) I must say I'm always fascinated by events like #BurnJita and #Delve2012 but it is something I will likely never experience firsthand - for I much prefer the great outdoors to the horrors of deep space... being simulated on a PC monitor.
To the victor go the spoils and to the spoils go Victor. He's the CEO of Wargaming and he'll probably buy up CCP at some point. That crazy tank-driving bastard has more money than Bill Gates.
