I think were going to have to write off the single player aspect of CLOD until maybe we get the SDK and let the community have a go, though even then i dont know if it will be possible to implement a decent career system.
If you consider a (dynamic) career system imperative then maybe.
Personally i remember the state of IL2's SP experience not being 'stellar' on release, it took several years of 'external developments' both in the dynamic aspects as well as the static campaigns before it 'took off'.
FSM's excellent campaigns for instance started around 2006 iirc, building on the previous work of the likes of Bird brain, Extreme one, Polymando etc.
Now IL2 did start from a better level- it certainly didn't take 9 months for working out how to tame the worst excesses of AI
but i still have hope that some of the clever people out there can come up with something- Desastersoft for instance have something approaching a rewards system (medals, another way to get reports from the radar).
