Its a very refreshing and bold design for the developers of the 7 
wonders series, as it was almost toally a facelift or a gamelift. 
Surprising better and better with every series. Previous series is just 
building the main monuments, but THIS! Building the main colony (or some
 such air thingy buildings) and lots of decorative things (as mentioned 
flowers, trees, ponds, its kinda of almost endless), and lots of 
buildings for your space areas, eg, landing pad (which u would encounter
 in the 1hr trial, so I am not giving away spoilers that didnt appear in
 trial). 
 Game can be played in 4 different modes : Insane, Difficult, Normal and
 Zen the latter being untimed so the game will be suited to everyone 
from beginners to the seasoned Match 3 players. Room for various 
profiles so the game can be shared. I encountered no tech problems in 
the hour demo. The cursor was nice and stable, which wasn't the case in some of the previous 7 Wonder games.
Gold to be earned to buy various items to decorate your village, love 
this added feature, achievements to be reached, different sort of power 
ups to be won. Good explaination on what everything was and what its 
purpose was etc, even a bit of history on each location.
