I would only support the Career Mode Multiplayer.
Why?
Generally said I am a Sim Player.
I play World War 2 Online currently and I hope the Enigma will give me what WWIIOL doesnt:
- Naval Gameplay which consists of more then camping enemy towns with DDs while the enemy ground troops have nothing to fight back and air can't really harm you due to the bad damage model
- more then 2 ships (it does already

)
- persistant ships, why are really are produced with a countries resources, if I sink a BB I want to have accomplished something and don't want to see a new spawn 30 seconds later
- reasons to fight, I don't want to sink enemy ships just for the heck of it, when I sink an enemy freighter I want to say to myself "this could have been 2 torpedo boats which could have sunken me in two weeks"
- French ships! I hate the german tincans
However I hope it offers what WWIIOL offers as well:
- a "bigger picture", I don't want endless fighting without an end, I want a way to win to win a round and if its just by "controlling 80% of the sealanes"
- the "bigger picture" should be player controlled, I want player controlled command structures (or high commands

) making the dicisions where to send which fleet and which route to use for supply
- one server with a persistant gameworld, I want to stay up in the morning and see what my american comrades accomplished over the night
- I want the ocean modelled on a 1:1 scale
Short Version: I want to play a real war and not Quake on the Water
Oh, and 1$ for 24h is way to much.
Most online games don't cost more then 15$ a month.
