Query: 2nd Installment Is Amazing

A truly quality game, RA has survived for years because of its gameplay and resale value. The second in the CNC series, it provides some WWII mayhem with a twist. That twisted NOD dog Kane has gone back in time, and from the opening screens you know you will be in your seat for a long time. It offers a skirmish mode, which the first one didn't, along with a map editor and two vastly divergent campaigns, Soviet or Allied. The cutscenes are of remarkable quality (the Stalin actor is dead-on). The story goes: Einstein's time research has led to the development of a time machine. He goes back in time and kills Hitler, but makes history worse, as Stalin and the Red Army now want their breathing room. A momentous game that spawned an entire genre of copycats, this game holds up still, and now it is being packaged with RA2, also a very fun game. Just get this game, it is great.
