I was  thinking after I started the longest and hardest games thread that there should be a thread for all extremes in games. For examle the best worst easiest or shortest etc. Add your own.

Extreme fun:
SMG :P

Extremely confusing:
Final Fantasy VII plot, especially with Cloud's memory. Great game though.
Extremely easy to understand:
Mario series plot. Save the princess!

Best Game:
The Legend of Zelda: Ocarina of Time
Worst Game:
Shaq Fu

Worst Translation:
Zero Wing

 I agree LoZ:OoT was my favorite game too.

Longest Ive played-The Elder Scrolls IV:Oblivion
Shortest Ive Played- Metroid Fusion- I beat it in around 1hr 45 mins the 3rd time
Hardest-I can't think of it I have to figure it out. Probaly original zelda but after a while you get the hang of it and it is easy.
Easiest-tetris
Best-LoZ:OoT/Metroid Nes
Worst-I don't buy bad games so Idk. I only buy games that have good reviews or my friends say it is good.
Most Gory-Gears of war
Most Boring- Brain Age this game bored me after like the first day
Most Interesting Story- LoZ series Im still confused on the timeline because Nintendo still didn't release one but the story always has twists and is my favorite
story ever.
Best Online- CoD 4 I love how you lvl up and how there are so many options to play from team deathmatch to Capturing bases
Best Multiplayer- As of now ssbm but that could change when I get brawl.

I think that Super Mario Galaxy is the most creative game I've ever played. The amazingness never ends!

Longest Game: LoZ:OoT
Shortest Game: Resident Evil 4 (after you've beaten it a couple of times)
Most over-rated: GTA and Brain Age
Game I spend too much time playing: Guitar Hero III

Best intro: Sonic Adventure
Best Music: Majora's Mask

Extremely addicting: WoW

EDIT: Please note that I do not play WoW, but I have a friend who does, and it has consumed his life. 

Most funniest: Conkers Bad Furday
Most longest: The elder scrolls: Oblivion
Best music: Sonic Adventure 2 battle
Most Gory/discusting: Gears of War
Best multiplayer: Halo 3, COD4 and the Battlefield Series
Most long lived: Battlefield 2
