I've read the entirety of Mass Effect: Nova and The Elder Scrolls: Vengeance of the Deep because they are both engaging and well-written narratives that I quite enjoy. I also read Pachamac's The Legend of Heroes: Tales of the World for the same reasons. I feel engaged not just by writing but reading, I don't have to be participating to enjoy a good thing. Sometimes I like to pop in the OOC, but few tend to enjoy a reader's input I guess? Either way, I see no problem by it. Though, I did just join Nova so I guess that doesn't count anymore.
