I've been playing World of Tanks (wikilink*) for just over two months now (seems like forever) and have some decent vehicles in my garage. I have just fought my 100th battle in my KV13 Medium Tank, and hope to change that for an IS Heavy sometime in the coming week. I've been in over 500 battles in my T34-85, and am within about a hundred battles of being able to begin production of the T-43 (which line of development will eventually culminate in the T-54). For a bit of light entertainment I also have an SU85, armed with a 107mm tank killer, which I may or may not decide to upgrade to an SU122 sometime in the future.
I have of course kept my T34, and still enjoy charging around with it and its rapid firing 57mm gun. One can almost sense the surprise of some of those I bump into when I seem to pour shots into them twice as rapidly as the more normal 76mm armament would!
And I still have my MS-1, though hardly ever drive it now (these days getting my lower level kicks from driving my level/Tier 5 T34). It won't last much longer though, as after I replace the KV13 with an IS, I will need the 'slot' presently occupied by the wee MS-1 for my T43 unless I wish to sell off either my T34 or T34-85 (which I don't), or stop developing my line of tank destroyers.
All good fun, and all free. What more could one ask for?
