Final Fantasy IV
Made it to the final boss and was just absolutely murdered.
My party is in the low-to-mid-60s so I guess I'd need to get everyone into the 70s before I'd have a chance.
I'm not going to do that. Even with the fast leveling in the Pixel Remaster, the prospect of that amount of additional grinding fills me with dread. I am no longer a child in 1991 and I need to be at least a little more careful with my leisure time than that.
I shall consider this playthrough complete and catch the ending on YouTube.
Difficulty aside, there really is something special about this game: especially if you can cast your mind back to the state-of-the-art in the early 90s. Even today, the music is outstanding and the character staging during cut scenes is expressive and delightful.
I'm not sure I could recommend this to anyone today who isn't explicitly trying to explore the history of the franchise or genre...but if you are trying to do that, it's a real treat.
