I've been aware of the Final Fantasy series since the first game launched for the NES in 1987, but I wasn't really a fan until the 16-bit SNES releases. It wasn't until Final Fantasy VII in 1997 that the series became a mainstream success, and it's been part of the gaming culture since then.
Games of the Final Fantasy series tend to have vastly different moods and settings. There's usually a combination of medieval fantasy, steampunk, and sci-fi, but the balance shifts from game to game. Lately, the series has been leaning more towards the contemporary to futuristic end of the spectrum, but this trailer seems to be harkening back to the magic combination that made the mid-90s games so memorable.
