Ever since Nintendo introduced Fire Emblem to the 3DS through the wonderful Fire Emblem: Awakening, the world's been hooked. Embarrassingly hooked. The game series offers cool weapons, personalized characters, romance, plot, music... basically all that stuff plus dragons!
Fire Emblem: Awakening gave us the (new at the time) Pair Up system, where two units could occupy a single space and grant one another various stat bonuses.
Fire Emblem: Fates brought in several new weapons and classes, granting the player unlimited game possibilities. You could have a character ride a dragon or be a maid - it's all up to you!
Fire Emblem: Echoes showed us Mila's Turnwheel, allowing the player to turn back time and undo a mistake that might have cost them a valuable unit. Moved a pegasus rider too close to one of those overpowered bow units? Well, you have the opportunity to change your fate!
Fire Emblem: Heroes and Warriors brought nearly every previous Fire Emblem game together to fight against a common evil and save the world. Heroes brings in politics of warring countries while Warriors melds canon with its own to create something brand new.
Not enough games being produced these days are single-player, plot and character driven with voice acting and amazing graphics. Well, hello Fire Emblem: Three Houses!
