As for me I mostly enjoy World of Tanks primarily because of the sheer fun you can have with your friends and clan members (wot-uni is an amazing clan with a highly friendly community). It's all about teamwork.
I'm as always hoho96
over there. Oh and you can find me on TeamSpeak on the adress ts.wot-uni.com
(no password). There're a couple of rooms for public if you don't want to join the clan, but hopefully you do eventually
I have War Thunder though i didn't get much into it (and for some reason i dont get a good ping with their servers)
I'm currently hyped for World of Warships with their public Beta on the horizon ^^
I've never liked World of Warcraft and such. And certainly not LoL.
I feel more of a heavy machinery fan in this regard. But I still enjoy fantasy worlds in RTS rather than MMO (yay Edain!).
