1: Yoshi all the way. I just loved the way he dances and I find him too adorable. :3
I also loved using Koopa Kid (not Bowser Jr.

) as well if Yoshi wasn't available for me. For some reason I liked having the Team "Dino Cousins" if I did teams.
2: I absolutely LOVE Brighton & Twila. I loved the day & night mechanic they brought and they were very unique to me. I would love to see them return somehow.
3: Should be obvious. Ness and Lucas all the way. I also love Breloom, Umbreon, Togekiss, and Kirby as well though...
4: Skip, I don't really have one. =P
5: Mario Party 6. That one was my freaking childhood and I loved EVERYTHING about it. The boards and mini-games were great (which I find the others didn't do, most of the others only had 1 or the other or neither LOL), and I absolutely LOVED the Orb system and the Day & Night feature. I'm a total nerd about Mario Party 6.
6: E. Gadd's Garage or Faire Square from Mario Party 6. I love E. Gadd's Garage scientific theme, and the Orbs available there were awesome. I had traps everywhere and it was easy to rake in coins.

Faire Square I love cause it was the first board I played in Mario Party 6 when my friend brought it over. I loved the concept of buying multiple stars and with the Orbs available it was very easy to get coins. I get so many Stars there... XD
7: I have too many to list... Though I'll say Granite Getaway, Snow Brawl, Mario Mechs, Rocky Road and Tumble Temple are in my top 5.
8: Hm, I don't really know if I have one... For generic enemies, I'll say the Hammer Bro family, and for non-generic, I'll say Amazee Dayzees & Duplighosts.
9: Paper Mario: The Thousand Year Door. This game was my childhood, and EVERYTHING about it was magical. I love acing it with ease cause people look up to my skills in that game and call me a hacker (not to brag) LOL
10: Reverse Mushroom, Boo Repellent/Gaddlight and the Plunder Chest. Reverse Mushroom is VERY useful cause it opens up a lot more options and you can be creative with it. Boo Repellent/Gaddlight cause people always go after me with Boo attacks and I like being protected from my Coins/Stars being stolen. Plunder Chest is VERY useful cause it essentially gives you control. Just by having it, your opponents will be forced to buy weak items, or risk having powerful items stolen and being used against them.
11: I absolutely LOVE the Kamek Orbs cause it gives me a sense of control and I love seeing an opponent's trap being used against them, especially something like a Piranha Plant. Piranha Plant also deserves an obvious mention cause stealing 1/2 of your foe's coins is a blessing, especially when they have high amounts of coins. Sluggish 'Shroom is also useful cause you can pretty much decide what happens on your next turn and will save you. Boo-Away Orb is also useful as I tend to be a target of Pink Boo attacks.
12: Hm, I'll go with the Action Time at the top left in Deep Bloober Sea from Mario Party 3 since you can keep visiting Boo if the arrow points to the right.

There's also the Snowball fight and Ice Skating on Snowflake Lake that I love, and the Trap Setter on E. Gadd's Garage.
