The general plot dialogue in the game is done using common real-time algorithms, where two character models face each other and converse, occasionally accompanying the dialogue with corresponding actions and expressions.
By today's industry standards, this approach has become routine, whether in AAA single-player titles or higher-tier online games, generally adopting this method.
However, Nitiandang's system clearly had more detail, richer animations, and more natural camera movement, providing a better sensory experience.
Furthermore, the game's text content was fully voice acted, which presumably involved top-tier voice talents. While not especially stunning, it achieved a level of non-awkwardness that was among the best in the country.
Of course, for a financially robust company like Nitiandang, good voice acting is to be expected and not particularly praiseworthy.
