Tonight I finished Red Alert 3. I gotta say, it's a lot of fun, and pretty much exactly what I want in a real-time strategy game. First of all, it doesn't take itself seriously at all, which I love: attack bears being shot out of cannons, Russians going back in time to assassinate Einstein, floating Japanese schoolgirls with terrifying psychic powers, David Hasselhoff as vice president of the United States, and the Shogun Executioner, a massive triplet of robots joined at the hip wielding massive lightning swords. The single-player campaign is a lot of fun, with fairly balanced difficulty and a wide variety of different types of missions. Unlike what seems like the majority of RTSes, it's easy to tell at a glance what any unit is and what it's for—this is a huge one for me. I'm always annoyed when I play a strategy game and everything looks so much alike that I can't tell what things are half the time. Red Alert 3 also doesn't rely on too much unit micromanagement, which I find very pleasing. And most notably, all three campaigns are designed to be played by two people, either you and a friend over the internet, or you and a computer-controlled co-commander that acts autonomously but can be ordered around as necessary. That system actually works surprisingly well in practice, though I haven't actually played with another person.
Anyway, I recommend it if you're into the whole RTS thing. It's gorgeous, silly, amusing from start to finish, and has heart that you just don't find in a lot of games. I'm rarely this gleeful when playing a game.
