User blog:Freezing Mike/Writing

As I've seen different ways to write certain names, I was wondering, which way is the more preferred one ?

Splicer, is written ingame in diaries and messages as splicer, but the description for a dead leadhead splicer is Leadhead Splicer.

Various other types of splicers.

Plasmids, are written ingame as plasmids.

Audio Diaries, are noted as diaries in the help menu, but ingame as Diary.

BioShock - BioShock.

Etc.
