Let me try
Wii
1-Super Mario Galaxy games. It's not only fun, but also a true example that with good art direction, a less powerful console can have games that look as good or better than most of the games from the competition.
2-Xenoblade Chronicles. An unexpected game that left us wondering how such a game could exist on the Wii but also a prove that Japanese devs aren't dead, it's just that most of them are just doing it wrong. Yes, that goes for Square-Enix.
3-Endless Ocean games. A slow paced yet addictive (not the right word but I don't know how to express it) game. And it's really beautiful.
4-Zack & Wiki. I know that it's not one of the best games, but the many imaginative uses for the wiimote (and most of them even worked!) hasn't been beaten by anyone.
5-Wii Sports. A true showing of why motion games can work if done right. Simple, fun and addictive.
Xbox360
1-Forza games. A great franchise that has top quality graphics and that'a funto play. Some want to compare it Gran Turismo, but the gameplays are so different that they can complement each other.
2-Gears of War games. Visually impressive games with very good gameplay.
3-Ace Combat 6. A great game on the series, enough said.
4-Crackdown. A sandbox game with cell chaded graphics. It had its flaws, but it was something new, with the character evolution, that made it different from any other game of the genre.
5-Viva Piñata series. What?! It's fun and challenging. What else can I ask for in a game?
PS3 (console I don't own)
1-Uncharted saga. Being a modern Indiana Jones while shooting the villains? Sounds good to me.
2-God if War 3. Completely over the top (sometimes it goes too far with the gore) and sometimes frustrating with the little platforming it has, but always an experience.
3-Infamous games. I like sandbox games, and if you add superpowers ...
4-Journey. I've read positive things about this game. I'd like to try it to see if they are true.
5-Gran Turismo. I'll be honest, I find it a bit boring. I know the "fun" is in driving well and all that. Thankfully, there's the arcade mode.
Please excuse my bad English.
