I've decided to call it a day with Final Fantasy IV. I have to admit, I began to like it again once it was clear I was almost finished. I got through the final dungeon without much difficulty (although I did give the bonus bosses a miss) but was dismayed to find out that I got absolutely pasted. This was at roughly 13 hours. I decided to level up.
I also went around and got a couple summons for Rydia, too, now that I was a higher level and completely breezed through Asura, Leviathon and Bahamut. It was almost fun! But after two hours, and gaining 10 levels I attempted Zeromus again.
And got smushed. Again.
I am not happy. I do not wish to grind out another 10 levels to maybe be able to scrape a win. It's a pretty cheap way to get longevity out of your game to make the final boss so much higher in difficulty than anything else. I know it's meant to be a challenge, but at level 53 I get destroyed within three turns. I think I even prefer how Final Fantasy X did it, with a final battle you can't even lose, and that was massively underwhelming.
It's a shame. If the ending hadn't been so grindy I would've happily beaten it and given it a 4/5, but as it is I can't happily give it above a 3/5. I wanted to beat this, I really did, but I can't forgive enforced level-grinding just before the end in a game I've breezed through up until that point.
