What are Gaming greatest trilogies?

[Hawki]

You did not ruin my day by nitpicking.

Damn. I'll have to try harder next time.

I've only played one trilogy in gaming, so by default that's my answer(although I like them a great deal):

Ace Attorney.

For me it's easily Halo 1, 2 and 3. Those were the days, just playing team slayer over and over with my friends. Multiplayers never been that good for me since.
