Give some insight into your past obsession, and how your tastes have changed over time. For instance:

When I first got REALLY into video games, it was all about side scrolling adventures (i.e. Castlevania, Rush N Attack, Metroid) and RPGs. Once I discovered Doom 2, however, I became a FPS whore!

Nowadays I find myself leaning more toward fighters (Mortal Kombat, DOA, Guilty Gear) and games that are in " quirky" genres (Guitar Hero, DOA: XBV).

I also find myself a little more interested in 3rd person games (Tomb Raider, Lost Planet demo), but if given the choice (Oblivion) I' ll take first person, anyday.

I also used to play the occasional Sports title, but not anymore. Oh, and I was addicted to Tetris for a while on the Gameboy. Actually, my friends and I have been hooking up the DS multiplayer Tetris, lately. Man, is that fun!
