I have to second Tarot's thoughts, and let me add that when the Storyteller's Guide comes out, it will read under a section called "Tense" that Mizahar is a game played in third-person, past-tense, omniscient narrator mode. And like Tarot said, please don't be offended by my saying this. It is not being said to hurt anyone's feelings.
Now, that being said, give me a chance to outline why this is so.
Past tense offers far more tools than present tense. With Past tense you can beautifully layer a story with flashbacks, narrative interjections, sweeping landscapes, without switching out of present tense to go to past tense. With present tense, you have VERY AWKWARD transitions which you are forced to make in order to go on an exposition of narrative or for characters to exchange dialog. So already you have strikes against it.
Present tense is often riddled with grammatical errors, awkward wording, weird transitions, and it doesn't read 'right' in my mind. I consider it gimmicky and find it really cheapens my reading experience. In fact, that is so much so that I usually stop reading present tense stuff because I find the grammatical tense errors (since often present tense writers don't proof or catch their tense switches midstream) soooo distracting that its not worth my time to finish reading. Present tense works well for really small choppy things, but when you want an epic, sweeping, panoramic stories - stick to third person omniscient.
Why? Wikipedia has a good answer for that.
This is a tale told from the point of view of a storyteller who plays no part in the story but knows all the facts, including the characters' thoughts. It sometimes even takes a subjective approach. One advantage of omniscience is that this mode enhances the sense of objective reliability (i.e. truthfulness) of the plot. The third-person omniscient narrator is the most reliable narrator, or in any case, the narrator least capable of being unreliable—although the omniscient narrator can have its own personality, offering judgments and opinions on the behavior of the characters.
In addition to reinforcing the sense of the narrator as reliable (and thus of the story as true), the main advantage of this mode is that it is eminently suited to telling huge, sweeping, epic stories, and/or complicated stories involving numerous characters.
And I don't know about you... but I write here on Mizahar for the epic sweepting tales... not the constant bombardment of "I did this. I said that. I went there. I squatted here." It just gets.... ugh! Ugh is a great word for present tense for me.
Also when your reading present tense as a reader, it has a different sometimes oddball rhythum. It's staccato. It makes readers more aware of structure and language which is a huge hindrance, because language mistakes under those circumstances are glaring.... I can't say that enough. I have two writing guides in my hand right now, and oddly enough, both describe present tense as a novel or story form of tense 'wearying' to read.
I know you write for yourself. That's true. But the fact is Present Tense is a departure from the beaten path. Some people will love it cause its cool and different. Others will hate it because it calls attention to itself and seems to shout "Look at me. I'm trying to be different - maybe too hard!". I know its to each their own....
Right now, I'm writing with a PC as a PC that routinely switches tenses midstream. He's a fabulous writer and I really adore his effort and his content, but when he keeps mixing and matching present and past tense, it distracts from even the most artfully posted episode.
So, hopefully you can see why I go UGH about Present Tense. And you can see why Mizahar has been designed to be and is definitely third person omniscient and always will be.
edit: for grammatical errors... its 2:30 am!
