Breath of Fire in general never gets much attention, though among the fan community, IV is ranked rather highly with only BoFIII standing in its way for being considered the most popular. Honestly I would say Dragon Quarter is more deserving in that fandom, since it is a very good game but is largely reviled by most of the fanbase and considered the game that killed the franchise.

In terms of personal favorites for me, Persona 2 is starting to become like this. I'll concede that Persona1 is kind of an experimental clustersmurf that's more enjoyable as a train wreck than as its intended purpose of entertainment, and I'll concede that Persona 3 took the franchise in an exciting new direction for the franchise and P4 improved on it, but it just seems to me like no one ever talks about Persona 2 or acknowledges what it did for the series, especially egregious when you see how much P4 and now P5 are copy/pasting ideas and concepts from that game. Most who have played it even say its a good game, so its not like the gameplay is detrimental.
