Seeing how this is a forum for VISUAL novels, I think all the "writers" that have been arguing about first versus third person writing are severely misguided.
In terms of novel writing, some professionals may prefer third person over first, so they can provide a vivid description free of the muck that comes with hearing it through the voice of a character, but these are VISUAL novels, I must remind. If you go into a VISUAL novel expecting to write the next great piece of novel literature, you have a seriously skewed view of the genre.
I think it's funny no one has noted some of the best VISUAL novel writers, Kinoko Nasu, Jun Maeda, the writers at Leaf, Navel, Circus, etc.
The best VISUAL novels were almost all written in the first person. VISUAL novels as a standard almost have to be written in the first person in order for the player to be able to better relate to the main character.
Tsukihime, Fate/stay night, AIR, Kanon, Clannad, Little Busters, To Heart, Da Capo, TokiMemo, Utawarerumono, Shuffle, Soul Link, Baldr Sky, Otome wa Boku ni Koishiteru, Chaos;Head, Saya no Uta, Kira Kira, Princess Waltz, the list goes on.
Most of these VISUAL novels had main characters that weren't supposed to be the player, they had their own styles, voices, personalities, etc. that made them unique. These VISUAL novels were written in the first person in order for the player to get a more intimate relationship with them.
This thread was funny, but now onto the topic.
I find something I've always liked reading in VISUAL novels, as well as try to incorporate into my own style is less a focus on the descriptions of the world, and setting and more a focus on the thinking of the main character. The VISUAL aspect of the VISUAL novel should do most of the VISUAL work for you, so try to focus on what the MC is thinking about and how he's seeing his world in his own world.
You can get away with a lot if your MC has a really strong voice that makes him sound like an actual person and not a writer describing a scene.
