Yep. FF1 on the NES had me addicted. Even borrowed my cousin's Nintendo Power strategy guide at the time. There was a group of about a half-dozen of us who got heavily into it.

And yes, the NES was my first gaming platform. FF was probably the third game I ever finished, next to Metroid and Castlevania 2: Simon's Quest (both on the NES).

Also had the first Dragon Warrior (now Dragon Quest). I also borrowed Dragon Warrior 4 (which I probably enjoyed more than FF at the time).
