World of Tanks, have been playing it for over 5 years now.
It's a team tactical shooter with MMO elements where you use various in game currencies to get higher tier vehicles and various kinds of equipment through a tech tree and also develop skills for your crew that will improve some aspect of your vehicle.
It is not based on your reflexes and how quickly you can aim at the enemy, it's more about getting to an advantageous position where you can exploit the map and your tank to overcome the enemies.
Game mechanics can be a bit complex, after 2000 battles you still know nothing, you start to get some things after 7000 or 8000, from 15000 matches on you are probably understanding all mechanics in real time and can start to be a good player at top tiers. Extremely experienced players will have well over 100000 battles.
