R.U.S.E. is a strategy game that presents you with both authentic and "what if?" battles from the second world war.

Playing first as a plucky Yank (assisted by acid-tongued Englishmen), then as General Major Erich von Richter, the Wermacht's finest, on his way to invade Britain, maps become larger and more involved until you're fighting full-blown wars complete with your own supply line disasters and surprise attacks.

Afterburner 3D
Back in the eighties and the early to mid nineties, there were a ton of classic arcade games. One of the top developers of some of these Arcade Games was Sega. One of the classics from the late eighties, that not only looked amazing at first glance, but also contained lots of action, was After Burner II.
