What's your favorite game series, and what's your favorite from each of them?

Kirby (Return to Dreamland and 20th anniversary Dream Collection)
Minecraft
Touhou (All the games, but the fighting games are fun)
Super Smash Bros. (All 3)
Animal Crossing (city folk)
If you can't tell, the only consoles I play are Nintendo.

Sonic The Hedgehog (Sonic the Hedgehog 3, Sonic Unleashed, and Sonic Generations.)

Touhou (Embodiment of the Scarlet devil, and Imperishable Night.)

Infinity blade (1)

Planetside (2)
Super Meat Boy
Team Fortress (2)
Serious Sam (Second Encounter)

Zelda (The question is not which one is my favorite, but which one isn't. That award goes to the abomination that is Spirit Tracks. Yet I played them all...*still hasn't finished Zelda I + II for some reason*)
Golden Sun (All)
Fire Emblem (I haven't played many of them but I did like Shadow Dragon the most cause of Wi-Fi)
Xenoblade (because who doesn't like a 140 hr long story campaign? Yes that 0 is not a typo.)
The Last Story (I give the mechanics a 10/10, Story...6.5/10)
Star Fox (I've played all but the very first... Adventures and Assault were more my favorites, but 64 will forever be the best.)

Mario Tennis (Power Tennis Wii version)
Mario Golf (GBC and GCN)
Mario Sluggers (The one on the Wii)
Sonic (SA 1: DC, Heroes, Shadow the Hedgehog, SR 1 + ZG, Secret rings, Black Knight, Unleashed, Colors)
