Yes we need more pieces... the more the better!
The ruin pieces are just as flexible - nothing about them has to be a temple... I use them for retaining walls, and lots more. I don't build much in the way of 'themed' areas and thought the SA pack was great in this regard - SUPER flexible.
Exactly there are a lot of uses for building pieces.
Isn't that part of the fun? Creating a zoo, that doesn't exist in RL. I don't think the view of the common zoo should be a standard for DLC. Or even common view on certain building pieces (you mentioned temple) to be used that way?None of that screams 'Zoo!' to me
We have a small zoo near our hometown, that focuses only on Indonesian animals and almost every part of the zoo has that theme or a lot of buildings are inspired by this.
And another big zoo near our hometown, had a focus on rides (even a rollercoaster) but tbh - moneywise not a good idea
