Has anyone with a T-Pack invested the $29 on the content starter pack? Looking into this to add to the limited content Vue Fantasy came with, however, I am kind of reluctant to spend $29 not knowing exactly what I am getting.

I've looked on E-On's site, under the other programs for information because it is my understanding that the contents of the starter pack are included with the higher versions - but their description is rather vague as well. 

" ...... 190 3D objects (of which 18 animals, 28 buildings, 5 characters, 21 vehicles, etc) as well as over 50 additional plant species and 10 new sets."

Anyone know if there is a list out there?

It contains the Vue Artist line objects, and the default plants. Objects are useless, they were probably made at the time of Vue 3 (if not before!), but you'll want the plants, even if the quality is far from consistent between species (some date back to Vue 2!), but they are needed if you want to buy some of the plants from Cornucopia.

To know exactly what's included, download a demo of Vue Esprit, and check out the collections.

Well, ... lets just say SOME of the objects are useless. Some of the earliest objects are quite good - they were made by professionals on commission to E-On. Higher modelling standards than I was able to reach at the time.

As Bruno says, the plants are easily worth more than is being charged for that pack in its entirely. A pretty wide selection of trees.
