I haven't looked at the others but they probably ask as much for the same feature set.
They all share a common set of features found in the basic game.
The two higher levels offer less help, although it is always available, and the full set of features.
I think the feature set is also fair game at this point.
Each named unit is a set of features and their values.
But in the second order system they take on a different set of structural features.
These projects aren't just another product with a different feature set.
Each provide access to a specific set of features and functions.
If it were only about feature set, I would have switched to something else long ago.
"Now we've hardly one whole set of features between us."
