Clash of Clans
I don't know anything about this game, but I find the ad mildly amusing, and I like the archer girls. Then there's an ad featuring Liam Neeson.

Far Cry 4
I don't care about the game, but the ad is awesome because it features Donald Glover and Danny Pudi from Community.

GameFly

Hot Wheels
Challenge Accepted.

LEGO
"Rapunzel"

Nintendo
Mario Party DS; then an ad featuring "Believer" by Imagine Dragons.

Peek-A-Boos!
I really don't want to like this ad, but I can't help it. I find it too kawaii to dislike. (But I'll totally understand if anyone else finds it annoying.)

PlayStation
"Grandma" (one of several "Dear PlayStation" ads, this is my favorite), then Crash Team Racing (which I find memorable for Crash Bandicoot saying "Booyah Grandma"), then "Perfect Day."
