Fire Emblem Path of Radiance is exactly what a FE game should be, imo. Its the first one I played and I played it over so many times, its imprinted on me what FE should be. Fire Emblem Radiant Dawn is almost as good but not quite. I played all the 3DS games, they are just ok to me. Too many of the changes broke 'proper' FE mechanics/systems.
Fire Emblem Three Houses at the start I thought it was a step back in the right direction of the GC/Wii games. But longer I played I found more things I didnt like as much. The monastery become very repetitive like Perona games. If they streamlined the entire month in to a week of gameplay it would have been better. The lack weapon triangle took away some strategy, even if they just nerfed it down a bit instead of complete removal.
Mostly just gripes but overall really good game I enjoyed my time with. I will go through other routes but not in continues play-through, it will be pick yup and play game in times of boredom.
