I'm okay... after downloading everything and exploring the "manual", I can see that this is going to be too complicated for me.
Also, all the discussion of buying upgrades and "real money" has me thinking that this has the potential to be another nickel and dime drain.
Finally, I cannot seem to find any way to practice moving around or operating the tank on my own. I am not too likely to enter battle with actual people without any clue what I am supposed to be doing or... even how to work the tanks.
Anyway. It looks like fun.
