if you want to, sure. though
Player of Games or
Consider Phlebas would probably be better starting points.
Quick summaries; Cormacaroni, feel free to correct or expand.
Consider Phlebas - Hyper-epic space opera on a frankly ridiculous scale. Galaxies collide, civilizations fall, trillions die, etc.
Player of Games - Political intrigue about a professional games player who's sent on a special mission by the Culture to WIN IT ALL. The "rompiest" of the Culture books.
Use of Weapons - Incredibly complex psychological drama that focuses on an ex-member of "Special Circumstances" coming to grips with his past. My favorite, but possibly a difficult starting point.
Inversions - More of a political fantasy novel than a Culture novel, though events transpire that make it clear this world is set in the Culture universe (and that the Culture may have played a part in how things transpire.
Excession - A probe enters our universe from outside our universe. Then it leaves. Then it comes back. The Culture and The Affront (the hilarious warmongering anti-Culture) both vie for supremacy. What happens when an unstoppable cannonball hits an immovable post?
Look to Windward - The Culture intervened in a planetary war, thinking they Knew Best, and caused a massive genocide. Oops. They feel really bad about this.
Matter - Not sure yet, just started!
The Culture is awesome, awesome is The Culture.
