I personally think this Game CAN be fun. If you're a player that just plays the game time to time and doesn't care too much about the game's progressive system and vehicles, then yeah maybe you will have fun. The game looks good, it runs good (mostly), and it certainly feels good.
HOWEVER, as a player that has spent over 2000 hours on the game, I can certainly say that the game is REALLY addictive. If you are planning to play this game like to get some cool vehicle someone was talking about like the Tiger Tank or the F14/F16 jets, then be ready for a damn grind in a half.
...note, don't forget to pay in premium because you barely can't progress without premium xp or even get the cool premium vehicles....
The game is a free to play game, so it's intentions is to get money off of you and to get you addicted. The grinding system is a perfect example. If you're just starting off, and you want a really advance vehicle like the Abrams or maybe a cool jet? Well, that can take a lot of months or even years. So, how do you progress to make your time short? Well you either cough off some cash or waste your life grinding away.
The reason why I'm deciding to quit the game now is because I'm really addicted to the game to the point I have some mental issues. The game has taken years of my life and I cannot continue playing it. Maybe it was my fault for treating the damn game as if it was a full time job or something like that, but I really don't care anymore. I've suffered enough. At the same time, I can't really complain because after all it's a free to play game, they need money through addiction.
Look, if you wanna play the game and try it out, you can. Invite your friends and I'm sure it will be fun. However, play long enough and get serious enough to grind, and maybe you'll fall in a loophole. I won't stop you.
