You should, those two games deserve to be platinum'd and appreciated to their fullest.
I will. And it wasn't just those two. Tons of games from Infinite Undoscovery, GTAV and Red Dead 2 to Vanquish and NSMBU (Wii U version). Something comes up and before I know it, a year has passed. In fact, I bought Xenoblade for Wii, didn't beat it and bought it again for the 3DS...only to not beat it! I suck sometimes.
