After 2 years of saying I was going to play World of Tanks on the PC I finally did last year and I was amazed by it, The original shell of the game for people who haven't played it appears as just a simple tank shooter game but the reality of it it much much different. The mechanics of everything and learning them can be daunting for new players and lead to 100's of games barley hitting anything or getting kills before you can even grasp what to do.
After playing for 6 months with 2.5k battle under my belt I finally consider myself a decent player even in comparison to many im still the spring chicken at 2.5k, battles player and after many hours reading up and watching videos explaining the mechanics I still learn new things all the time, During this year I've moved my focus away from PC gaming a lot and this was about the only game I missed at times and now with the Xbox One launch it could be time for me to get back to it.
TLDR: The game is unforgiving with a very steep learning curve but spend a bit of time learning it and it will blow your mind and you will understand why it is such a great game.
