Yeah, the solo stuff really isnt the main focus of the game. They are fun, but you dont earn much in the way of experience or silver lions, so it would take a very long time to grind through one vehicle, much less any of a nation's tech tree. This is a free to play online battle game. As such the majority of the game takes place online. I suggest getting you feet wet in air arcade battles before moving on to realistic as with realistic you only get one shot in one plane. Once your shot down, that round is done. For tanks, dont bother with arcade, just move right into realistic tank battles. Tank arcade is just a mess. I suggest picking up a month's worth of premium account, grinding through a couple of ranks of your country of choices tech tree and see what you think of the game before investing in buying any of the vehicle packs. If you have any more questions feel free to ask away, a few of us here have been playing this game since it pretty much was released.
