Anyways, on topic:
1. Should a Sims base game require EPs to feel complete?
Yes.
2. Which of these feels "complete" without EPs?
The Sims
3. Are EPs released too often or not often enough?
Yes, they are released too often, and they also split tons of things into unneeded "Stuff packs". Corporate greed.
4. How do you feel about the number of EPs that come out in a Sims game's lifetime?
Way too many.
5. What are your favorite EPs? Why?
Seasons, since, you know, its the one that makes the game realistic. STOP releasing it. Make it part of the base you greedy twits.
6. What EPs do you find redundant? Why?
Seasons and Pets. It should be in the base.

New features.

Stupid objects.
