In most games that I play, by the time I arrive at the final boss, I'm totally ready to kill him. Like, with Final Fantasy VI, there are plenty of side quests to do that get you well-leveled up, so by the time you've done most of the side quests, you can take the last guy, easy. Likewise with FF7 and numerous other FF games.
But with this one, it seems like everyone dies on their first shot at Zeromus. I've noticed that when I want to win comfortably, I have to spend A LOT of time just leveling up. Sure, I could probably scrape by without the intensive rigorous training, but I mean if I want to go in there and not have any doubts, it takes a LONG time.
It seems like the average gamer arrives at Zeromus with a party that would be dead after 2 Big Bangs. A lot of people also missed handy things like the Crystal Sword and the other out-of-the-way equipment.
So, who else lost to that thing on their first attempt?
