I know Gold Box isn't a single series but I don't care. The formatting sucks. I also don't care.
I only counted main entries, so no jap Wiz, Ultima Underworld or Dark Messiah.
From highest- to lowest-scoring:
1. Wizardry:
No points for II and III, unsurprisingly. IV plummeted, while I and V climbed slightly. I'm surprised that Proving Grounds earned twice as many points as VI. Who are these mysterious retro-gamers? Turning to the only non-retro game of the series, 8 dropping ten places is a bloody travesty, and I am much disappoint.
As a series, Wizardry dropped 73 places since the previous poll.
Points total: 283
Total # of votes: 107
Series average: 2.6
2. Might and Magic:
No votes for IX, not even meme ones. Only one, and a single-pointer at that, to VIII, courtesy of laclongquan. Slight improvements for I and II, which is a bit surprising to me, but doesn't really tells us anything while they're both so low on the list. The big change is III, dropping a whopping 85 positions from just inside the top 50 to outside the top 100. And only 2 votes, too. Maybe new voters have only played Xeen?
As a series, M&M dropped 172 places since the previous poll.
Points total: 206
Total # of votes: 90
Series average: 2.3
3. Ultima:
Not surprisingly, voters mostly went for the big four, with no votes for I, III, VIII or IX. Very surprisingly, II got a single five-pointer, from some new guy named Irata. Is he genuine? Who knows, he might be the only person on this forum who's played it. Ultima II the only game to make its debut on this year's list apart from MMX, which wasn't available last time. Also of note is the huge 61-place jump for VI, which sounds impressive if you ignore the fact that it only got six votes. Seems not many people go for VI, now or in the previous poll. I assume the points for VII include both Black Gate and Serpent Isle. Naturally, it's where most of the points went.
One huge piece of incline related to the Ultima series: unlike last time, Worlds of Ultima: Martian Dreams got a point! Pyreen, whoever you are, you're the man.
As a series, Ultima climbed 27 places since the previous poll, owing to the meteoric rise of VI.
Points total: 146
Total # of votes: 64
Series average: 2.3
4. Gold Box:
Terrible poll for Gold Box. Five pointless games, and three with only one vote each. Voters seem to have consolidated around Pool of Radiance, which attains a very respectable 26th place in the poll. Meanwhile, DQoK suffers the biggest plunge of any game on this list, dropping 101 places. Its single vote, and point, was awarded to it by the ever vigilant octavius. Dreadful business, dreadful.
As a series, the Gold Box games dropped 255 places since the previous poll. In fact, it probably dropped more than that, since these results don't account for games which dropped out of the list entirely, but I'm too lazy to check.
Points total: 111
Total # of votes: 41
Series average: 2.7
Some more hot facts:
Most popular game: Wizardry 8, with 119 points from 45 voters. For reference, that's more points and more votes than for all the Gold Box games combined.
Highest averaging game: Ultima II, with an average of 5.0 points.
Highest averaging game with more than 5 votes: Might and Magic II, with an average of 3.4 points.
Highest averaging series: Gold Box, with an average of 2.7 points. Considering the number of votes, however, Wizardry's 2.6 is probably the more impressive result.
In conclusion: they all did terribly, and we all suck.
