If you are interested in game dev, the first thing you need to think about after you have your concept down is the POV you want. Everything else about your game’s look and feel will be dictated straight from this point, regardless of how fancy or high tech the graphics or complex the plot. There are three POVs in gaming:
First Person: this is the way that we see the world around us naturally. The player’s view will be straight ahead, and the camera will need to pan from side to side to simulate the player turning his or her head. Many games use this POV because when done correctly, it can really “sell” the player on the reality you are immersing them in with your game. Your goal when creating the game is to have players forget about the distance between themselves and their screen; you want them to believe that what they see on the screen is what they’re seeing through their own eyes. Technically great graphics or photorealistic images and high-quality sound will help perpetuate that illusion. Many shooting style games are first person, as it lends itself to be more accurate for targeting and more realistic gameplay (i.e., looking through a scope). If not done properly, it can really throw off the player’s perception and make the game both difficult to play and potentially nauseating.
Second Person: this is a little less typical, and seen mostly in text based games. Second person narration relies heavily on the pronoun “you,” which made it so effective for text-based game immersions. Everything in the game is influenced by “you” as the character, so the plot will rely on things that are initiated by or happen to “you” as the player. Text based games are very low tech and old school, but can be combined with graphics and given more of a comic book feel. Second person visually may be harder to pull off, because you would have to create a second, non-player character as a witness to the game. There isn’t really a logical point to do things that way, but if you can come up with an interesting concept, it might be very cool and can set your game well apart from others in its genre.
The last, and most common, is Third Person. In this POV, the player can see the character that they are controlling. Most scrolling games fall into this category. You may or may not be able to pan around the character; it will depend on the type of game and the look you are going for. If you are planning on having characters run, climb, and jump a lot, it will be easier if the player can see their entire avatar for better accuracy. There’s a reason all those Mario games are third person!
