Last year I bought Boku No Natsuyasumi 4 (My Summer Vacation 4) for the PSP after a chance viewing of a trailer on Youtube (which showed almost no gameplay). I play the game as kind of a pallet-cleanser and sometimes just to poke around.
Now I don't really have any specific tastes in games, though I sometimes lean towards PC-centric titles (I LOVE space sims), but I'm pretty sure a game specifically meant to tweak the nostlagia-buds of thirty-ish Japanese men is pretty out of character. Look below for the trailer that cost me $55 (and a more in-depth video below it).
