>>65Eh, Mother 2 is bolder, but most of the time it feels like a shock and awe sort of boldness. 3 has a better narrative/gameplay on the whole, a grasp on subtleties of both. It's inches closer to perfection, and while Mother 2 certainly made me feel things at times, Mother 3 is the only game that's ever made me feel emotions as complex and involved as it did.
Everyone should play both for sure, though. Itoi is a wonderful creative mind whose work I hope to see more of in the future.
