Valkyria Chronicles is one of my big ones.
Also:
Ni no Kuni - 8 years
Lunar - 20 years (I was grateful to just get Lunar Remastered Collection)
Legend of Zelda - 3 years (no sequel in sight)
Ultima - 27 years
Fallout - 8 years (76), 10 yars (4)
Virtua Fighter - 20 years since VF5 originally released, unless you count FS, US, and REVO as separate releases
Kid Icarus - 14 years, but almost 40 years since it had an actual console release
Sakura Wars - 6 years
Star Fox - 10 years
Fire Emblem.- 3 years, but at least it's getting a sequel this year
Devil May Cry - 7 years
SoulCalibur - 8 years
Story of Seasons - 5 years since Pioneers of Olive Town, though since I didn't play Grand Bazaar on DS, I guess that makes it a new game to me
Final Fantasy Tactics - Not counting the remasters of Tactics on PSP and modern hardware, 19 years
Breath of Fire - 24 years since Dragon Quarter (I don't count the FTP game called BoF6)
Shining series - 8 years since Shining Resonance Refrain (which itself was a remaster of a 2013 game)
