Any love for Half-Life?

*edit*

Or Homeworld?

Kirby, and those who have a problem with Kirby Air Ride then someone has problems with me!

Dragon Quest~

Love or hate the style of the series, it always provides a skillfully made adventure. ;)

High five for putting Ratchet and Clank on the list! If we aren't including spinoffs (Secret Agent Clank), then I've never been disappointed by any of the games. Even Secret Agent Clank wasn't too bad though.

My list would be much different, but that's because I never got into like half of those franchises in the first place.

The Eight Series of Mario

Original Arcade (DK, DK2, DK3, Mario Bros)
Mario 2D (SMB 1, 2, 3, World, World 2)
Mario 3D (64, Sunshine, Galaxy, G2)
Mario Role Playing (RPG, Paper, Super Paper)
Mario Kart (SNES, GBA, N64, GC, DS, Wii)
Mario Sports (Golf, Tennis, Soccer/Football, Baseball)
Mario Party (1 ... 8)
Super Smash Brothers (N64, GC, Wii)

OK, on a real note and because no one seems to have mentioned sports
How about Winning Eleven/Pro Evolution Soccer

PS -- 10 Series that have come to disappoint would be more fun.

No Half Life, horrible list.

Where's Disgaea and Ace Attorney?

Usually anything Bioware touches.

I just realized that Halo shouldn't be on the list because of Halo Wars. That was a disappointment.

Oh, you mean that game that wasn't part of the main series?  I didn't play it, but I heard that it was actually very good!
