POLL RESULTS

After a little less then a month the poll is over; I think I have a pretty good idea of the overall situation.
The poll was asking which Expansion Packs people have.

140 people took part.

122 answered Seasons (87.2%), which is the most owned EP.
112 answered Open for Business (80%)
111 answered Nightlife (79.3%)
108 answered University (77%)
101 answered Pets (72%), which is the least popular EP
42 answered Base Game Only (30%)

The last number obviously cannot be true, since if 122 have Seasons and 43 have no EPs, we come up with a sum of 165, more than the participants. I think that some people have missed the word ONLY in the first option and have chosen Base Game, then ticking some expansion packs. If we presume that all those people only have Seasons, the new number for "Base Game Only" is 18 (12.8%), but it might be even smaller.
Anyway, this is what I learned from the poll.

1) Every time that I can, I will make my creations "base game compliant" (as I've done up to now) to let everybody access them, even those who have only the base game.
2) Don't make anything that requires Pets, which is the least owned EP; that's fairly easy, since I don't own that EP either, and I don't think I will buy it soon.
3) Get myself a copy of Seasons as soon as I can, so that when I cannot make something suitable for base game, at least the required EP is the one that will disappoint less people.
4) In all the other cases, I will use Open for Business and Nightlife as required EPs, since a good percentage of people have them.
