Besides the fact that it can takes hours and hours of farming in order to get something (Or you could just spend real money to buy it... because its THAT kinda game!), I would have to say this game sucks. From the "realistic" gameplay, the completely "balanced" factions, or maybe the "realtime" wars that players influence, I would have to say that it doesn't really live up to anything that it says!
Lets start with the free to play part! It, as stated above, can take upto weeks just to get enough money and XP to buy a weapon. However! If you think that you're above this, and don't want to wait, you can just spend the ~10 US dollars to buy it right there and then. (Buying it with credits even allows you to COMPLETELY skip over the XP requirements, along with the money!)
Then comes the "realistic" and "Simulation" battles- IF one could call them that! I believe that the biggest contender here is the movement model, which although had some nice hopes... is for lack of better words, sh*t. Many a times I have been in open fields or with large arm movement areas, when I get into a firefight with another soldier. Mid shooting, my gun pulls up and does the action that it does when your muzzle isn't in position (Because APPARENTLY my gun was running into some invisible force?) for firing. Then theres the maps... Oh! how I hate ALL of the maps. From large open areas with almost no cover from base to base, to the maps where it looks as though you must camp in order to be successful, or maybe the maps with overgrown areas with large amounts of fog? All in all, the maps aren't that great either, simply compounding upon everything else that is wrong in this game.
After that, there goes the "balance" which just as everything before is little but existent. I'd like to paint a little picture for you here...
American Bombing Planes: 2 bombs
German Bombing Planes: 1 bomb
Soviet Bombing Planes: 4 bombs! (Kinda crazy right?)
But, the German plane must have SOME redeeming qualities right? Like better mobility, or stronger bullets? Nope, its the exact same as the other, if not worse. After the planes comes the tanks and weapons. (I'd like to just say real quick, Germany is EASILY the most underpowered, and it seems that the developers neither intend to make it better, or debuff the other factions as they just recently added the Soviets into the game, which look to have the best weapons.) From the poor guns of the German, to the crazy one shot rifles and ludacris fire rate and accuracy of the American weapons, to the overly good starting Soviet guns, its blatantly obvious that the developers favor some faction WELL over others. Tanks/vehicles, while pretty well balanced, are VERY overpriced, and some seem to have the sole function of spinning in circles or denying friction. All in all, the game's balance seems to be lacking, and its actually rather annoying to see the devs. favor some factions over others...
Those "real-time" wars you were expecting? Or that "huge scale" battles that you thought you were going to get? Wrong again! While yes, there is a mega server that most of the battles take place on, and are ranked, most battles are only 16 V 16. This looks to be a rather small amount of people for all of the "class variety" that the game has, leading to searching for game up to 10 minutes (And thats without a squad... being in a squad can take AGES). Finally, after getting into a game, you may notice that THE WHOLE SERVER consist of just THAT class, or very few other... You can see that this leads to frustrating gameplay, and overly long searching time for a game that it may 'plop' you in, which ends roughly a minute after your joining! (Also, I'm not really going to approach the whole, campaign thing, as its seems to literally be pointless. Wars end within a day and most of the time it doesn't give props to the right faction... but you can almost always bet the Germans lose, even when they win?)
All in all, this game really in a trainwreck, that yes, I have had SOME fun playing, needs A LOT (and I cant stress enough how much I mean that) of work. Also, before you say, "Oh well you've spent almost 100 hours playing the game, it MUST be good!" I would like to state that I have only spent that much time in game because I wanted to be able to expierence a large portion of it so that I may give a proper rating and suggestions!
