Yeah, its good. Started a bit late. I first was doing world or warplanes, but found it a bit routine. Some friends have been playing WOT for a couple years.
They are already up to tier 8,9 or even 10. Most haven't paid into the game. Since its free to play with in app purchases, it can take a while to rack up the points and in game currency. The neat thing is you can platoon with friends. So far I have with couple friends. Using pcs or laptop in same room. easier to communicate. You can platoon with anybody and use teamspeak or skype even.
I am usually a spacer, but found this fun. Hoping worls of warships comes out soon.
It can be addictive. Just scratched the surface though. There are clans and you can play a stongholds type of game. which is more than a 15 min battle on a small map. it seems be territory type. I don't have that much free time. I can barely play my favorite games. Real life and all that.
