it actually all makes a lot of sense to me but it shows also that not only was i correct in my analysis but it also seems that the developers did rush the game and messed up a lot of basic issues and are humiliated by it!
First of to Emergency5 players: you can get 5 new campain missions, new freeplay scenarios and a Mass Intencive Care unit... yes it is a bit steep in price but it is discounted greatly for a limited time as much as they can but im sure working on new in game content and still trying to remove the bugs is costing the company in time, financial and human resorces.
Second, if you own EM5 but dont want new in game content then the EM2016 improved AI with enhanced pathfinding has been added as a patch to the game as it kinda was necessary.
Now the 2 burning questions on everyone's mind: "Why has Emergency 5 been removed?" and "Why is it called Emergency 2016 now?"
The long answer is: because it is well know that Emergency 20XX spin off series has been a bit of a let down and disappointment for the Emergency games brand, to see the players, clients and fans turn arround and say Emergency 5 did not live up to the hype and was failing on basic gameplay mechanics was a complete embaressment and i'm sure the staff agreed, especially when you bare in mind this was part of the Original Emergency series.
It is better to down play something than to over hype something just to be shot down and make brand and company's repuation worse than it already was, so transferring the game's identity from Original Emergency series to the Emergency 20XX series is meant to downgrade the status of the game and in doing so preserving the Original Emergency series brand and it's reputation where as the Emergency 20XX reputation is not quite as good and so wont be as damaged.
The short and simple answer is: It may be a shallow move in attempt to preserve any reputation the game and devs have but it is also a safe move as Emergency 5's tragic flop remains nothing more than a memory and a few external reviews as affectively the game is rebranded and starting a fresh start....
...again...!
