I looked forward to Red Alert 3 because I had so much fun with Red Alert 2. However, while the increased variety of units and new emphasis on naval combat made the game more interesting, the campaign is extremely frustrating to play unless you have another friend to play co-op. The odds are stacked against you so high that the later campaigns often take several tries to get it right (even on easy mode). In addition, the tech tree is confusing, and the need to "upgrade" individual structures, construction yards, etc in addition to high tier tech structures make it difficult to build up your tech tree quickly, which only adds to the difficulty of the more advanced missions. Multi-player is fun though, but if you want to play the campaign, be prepared to be frustrated, a lot.
