You're kinda cheating with Okami but I'm just being pedantic.

I don't think I could pick a definitive top 5 but in this moment I think I'd say.

1) Left 4 Dead 2 - It's a game I always go back to and given that I generally hate FPS games it's an achievement.
2) Mass Effect 2 - Just immense all round.
3) Elder Scrolls IV - You can play it for weeks without touching the main story missions and not get bored.
4) Street Fighter 4 (and it's various iterations) - One of the best Fighting Games in years.
5) Bayonetta - Just ridiculously fun and insane.
