I have to agree with Okimosy as far as wanting ships, dynasties, and multiplayer.
In the past, Stardock has removed (or failed to implement) multiplayer believing they can either make a "balanced" multiplayer game, or a game with a ton of options in lieu of multiplayer. Why? I love this game. I'd love to be able to play it with my friends. My friends and I are reasonable adults, we can read what the game does well, and what it doesn't, and accept that this is not a balanced game. None of my friends have bought this game, and without multiplayer, they probably never will, which is a shame for me, for them, and for Stardock.
As far as Dynasties and balance are concerned: I agree with the people who don't want their heroes to die of old age (or period), but I also agree that it would be necessary to implement. I agree it should be an option ("A game is a series of interesting choices." - Sid Meier), an alternate game mode, and that it should explain itself fully in the selection screen so that the player can make an informed decision. Personally, I like the idea of Dynasties, and feel they bring more life to the game. However, there will be times I get sick of my sovereign dying, and play the other game mode. Simple.
On the same note, naval presence could be added. Having it as an option toggled at game start would allow people who like the idea of being able to perform amphibious assaults, trade by sea, and take advantage of all the strategic implications a navy might provide could have it. Those who prefer the land centric game we currently have now would be able to maintain that. Neither option is wrong.
On that note (on that note), I agree with GaelicVigil, allow the player to play with the features they want, and choose which features they don't. There's no reason the came can't offer more, especially when it has done so in the past. Hopefully, this can be implemented in the future in a way that is satisfactory to most. With this team, I'm confident.
