I'm not sure how I missed this thread, but I ought to weigh in, as I'll be doing the tallying again this year.
I would personally prefer to end the Port Rule. The Port Rule is just an excuse for being too cheap to shell out for a new system when a game has its big premiere on one system in a year, but goes back for sloppy seconds (and diminished attention) on other systems the following year. It's just like owning the debut system to begin with, but not getting around to it until the next year. It was still officially available in the debut year, when it had its best shot at ranking in. Technically, region-exclusive games in a given year can be bought and played anywhere in the world upon initial release, but those cases clearly lack official releases required for adequate attention.
Basically, situations like Minecraft and Xenoblade appearing for 3 consecutive years due to completeness, localization, or other issues are things to be avoided if at all possible. Note that alpha and beta editions are no longer eligible.
The LTTP voting has been underutilized and produces uninteresting data. It's an overhead hassle that distracts from the year actually being voted on. The desire to find out about missed games would be better served by simply going back to read previous GOTY voting and result threads.
Expansion packs and DLC that serve as expansion packs can count as individual titles. Mario Kart DLC Pack 1 yes, horse armor no.
If the mods want to require comments, perhaps it would be better for them to take disciplinary measures against members who fail to include comments? This would stop people from "setting and forgetting."
In terms of voting duration, I want to go back and examine the time distribution of posts in the last voting thread. I suspect that it's heavily front-loaded with a small, statistically-insignificant spike at the end. I'd prefer not drag it out with few votes happening in week 3, and the top 20 not even really changing in week 4, but some people would scream bloody murder at shortening the term, so I won't push it.
Fan translations are super-niche and rarely of new games from the year in question. These would receive far more attention in their own threads than a statistical blip that has to be maintained alongside all the Windows Phone exclusives. They're not even exactly official, licensed releases. That said, they're not difficult to include.
