Listen, MOTHER/EarthBound Beginnings isn't a very good game as far as mechanics go to begin with, but the last section, Mt.Itoi?
The aboslute worst.The main developer even confessed to not having balanced the last section very well. Ugh. More time wasted.
To give you an idea of how awful the situation in the screenshot is, let me explain what each party member's role is:
Ninten is basically the Tank/Buff/Debuff-er. Most HP, highest physical offense and defense, and works well as a backup healer.
Ana is the PSI powerhouse. She can destroy things easily (and is only a few levels away from an insta-kill AoE PSI), and she has the best healing PSI, but she's really fragile, slow and weak.
Both are the only ones capable of removing status ailments and restoring fainted party members. There are no status recovery items save for poison and cold (basically Poison 2.0).
What can Lloyd do? Nothing extraordinary, outside of being able to use gadgets. Not-so-good offense, not-so-good speed, no PSI, mediocre all around. The party's virtually defeated already.
To make matters worse, a temporary party member with no PSI but far more durable, faster and stronger than Ninten was recently booted with the whole "physical strength alone won't defeat evil" moral as you get Lloyd back. That's well and good (and actually true, but spoilers) but brute strength DID get everyone to the plateau whereas a repeat attempt with Lloyd instead ended in failure. Again. Poor Lloyd. It was his time to shine.
