I also will be VERY HAPPY if I could run DW on Linux. I still have Windows for playing games...
On the other hand, we allways want more!
We forget the great improvevment that is driving, not only different subs with different characteristics, but also a surface ship, a helo and a plane!
And we want more playable!!! When 688i Hunter/Killer or Fast Attack came, did we asked for more and more playable platforms?
DW still has many things to improve so, I think is better making a great game with "few" controllables than a lot of controllables than doesn't works fine (I want my Akula to go up without breaking the TA... and without surfacing!).
The only think I would change is add more countries. It will increase a lot the mission design giving us the cahnce of creating more possible scenarios. SCS only wants us to create missions (a great mission editor I should say, despite still needs improvements), so please, wive us more toys to play with
