Stellar tactical war game that isn't just more tanks
You play a colonel given orders from a general to invade Normandy, hold a line in the battle of the bulge, stop the German exodus and so on. In some scenarios, tanks are the answer, in others, artillery, some paratroopers, still others a combo. In the campaigns, you are given limited resources to meet your objectives. You don't have an unlimited supply of anything. The strategy portion comes in deciding whether to flank, drop paratroopers from behind, etc. You'll be tested and you'll enjoy the process'
Only have 15-30min to play? The skirmish mode is a lot of fun and helps builds your tactical fighting skills.
I highly recommend Order of War. If you're a newb, it's a great game to get started on. If you're a veteran, you enjoy the tactical fighting aspect of the game.
BTW, sound track and graphics are amazing.
