Just did a 2-3 month playthrough. Took 829 screenshots lol.
Going into Esthar there's this console you can interact with that controls the camo panels that hide Esthar. 6th or 7th time beating the game and I still found little details and new dialog like that.
I did a "battle almost everything run" and you know, the contention that "leveling makes the game harder" is bollocks. After you level enough you scale much more than enemies AND you have better magic, abilities, and items. It was significantly more fun than a low-level run.
