I'm counting FF because I started (but did not finish) the first game as a rental when I only bad an NES before getting a SNES and FFIV (which was also pretty early). Mario and Zelda I've also been with from the start. I'd say Mega Man too. I'd say Metroid but the original is actually the only one I've played. Dragon Quest might sort of count but honestly, I played the first game and then dodn't really get back into the series until DQVIII. Breath of Fire definitely counts for this, as I started on the SNES and went to PSX. Suikoden also definitely counts, even if it's a later series because I started with the first one before the second was released. Played through all five numbered entries and Tactics. Maybe thr last ones don't technically count because the series are dead but whatever.
