Great classic, something that you can't go wrong with. A great way to brush up for Red Alert 3 or other C&C titles.
Yuri's faction, however, makes up for nearly any minuses this game might introduce.
If you are the kind of sly, sneaky player, Yuri's faction is an amazing force. They introduce tons of more strategies to the already deep Red Alert conflict. The expansion also fix tons of glitches and adds extremely handy new features. This expansion + game, in my humble opinion, define the RTS genre.
If you have a friend to play with either over the net or LAN, then the replaybility is even more (amazingly). Great coop teamwork is rewarded by uncrushable forces (Yuri clones + tanya + Battle FOrtress?), or you can go head to head against the other player.
Lastly, if you are waiting for a soon-to-be-released RTS title, Yuri's revenge can help you with that wait with a high chance to satisfy your desire to command.
