The conventions of writing about video games are still being codified, so some explanation of my use of the point of view in this study is in order.
When discussing the game in general, external terms, I tend to use the third person to refer to the player, as in “the player is required to choose a race for his character” or “the player may want to save her perk choice until later.” I usually switch genders in order to avoid both the sexism of using one gender over the other and the inelegance of “his/her.” I also use third person to refer to my PC from an external player perspective: “I chose a stockier body type for him because I thought it fit my warrior-oriented gameplay.”
When describing general in-game events that are not part of my own gameplay, I most often use the second person, as in “in order to join the Legion, you have to prove yourself on a solo quest.” The inclusiveness and informality of the second person works well in these cases.
When narrating my own playthrough, I use first person almost exclusively, as in “I attacked the troll with a war axe.” I find that trying to maintain the third person, which would otherwise be appropriate for this kind of storytelling, both tedious and contrary to my project of discussing moral agency. “I chose to join the Legion” is more active and concise than “I chose to have Lothar join the Legion.”
As with all of my guidelines, stylistic or otherwise, I am sure I have deviated from these several times already.
