Getting Launch arcology in simcity(2013)?

I am Interested In getting the complete edition of the game given that I even own the existing Simcity(2013).

But only to be dissuaded to noted that a number of DLCs wasn't in the pack, namely one that I had been eyeing for a long time the "Launch Arcology" was reluctantly excluded too.

Missing the preorder was truely unfortunate on my part, now even after a year this wasn't even made available as purchaseable simply baffles me.

Surely, discounts may seems attractive but without the "Launch Arcology" DLC I see no means in getting/purchasing the expansion or continue the game.

However, if you do have means to get "Launch Arcology" DLC availble. Please do enlight me.

The purchase of "Cities of Tomorrow" is a sure go with or without discount as long as "Launch Arcology" is available for the grabs!
