Pros - One of the few tanks sims that exists. Limited but fairly accurate and enjoyable, with high degree of customizability for realism settings. Includes mission/map/object editor. Co-op multiplayer allows up to 3 people to command a single tank.
Cons - Confusing and likely not enjoyable for anyone who doesn't like simulators or has no clue about tanks/armored warfare. General clunkiness and quite dated. Good luck finding any user maps.
There is a demo for this game, if you're on the fence track down a copy and give it a try.
It's one of the few tank sims that actually exists so it doesn't have much to be compared to. It's reasonably accurate and entertaining but is extremely clunky and poorly programmed, going by how many loading screens you'll go through switching from menu to menu. Customizing individual graphical/realism options (other than putting it to low/medium/high/etc.) requires you to close the game and run a cfg.bat in the game directory.
Despite being old and with a questionable build quality I haven't had any mysterious crashes or other game breaking bugs or issues despite running it on windows 7 64 bit, which actually makes it more stable than other current titles I play. The only glaring bug I've found is that you cannot reload the coaxial machinegun at all, the only workaround being enabling infinite ammunition which also gives you infinite shells for your main weapon.
It's also quite challenging, and it's not helped by the default user settings having the enemy AI at quite a high level. You can't rely on your armor in the first few missions and will frequently have to restart due to your crew bailing out after a single hit. The AI will also spot you much earlier than your AI commander will be able to spot them. Thankfully there are a lot of options for realism settings and you can pick and choose until you end up with something you're comfortable with.
The manual has plenty of information but is missing one or two details like the penetration of munitions used in game, and it was probably also in color at one point and has not survived the shift to black and white.
There's nothing here for anyone who does not enjoy simulators, as while it is fairly streamlined compared to what it could be it still is a sim. It is only 5 dollars and there is not exactly a glut of other simulators to choose from. Find a copy of the demo if you're on the fence about it.
