What was the hardest battle you ever fought in any tactical RPG?
I have 2
One was in war of the lions where you face one of those esper enemy's i think i was severly under leveled i still beat the guy .... barely

The other was in D3 AOJ
I was try-ing to level in the item world then i went in too deep and got attacked by 2 high level pirates on a small level and ... got wiped out as expected...
