Sims have become higher fidelity, but for some reason lost the fun that should accompany it. Structured campaigns AND dynamic campaigns, stories, characters, various environments...
I guess it bouls down to spending money to do one aspect intensely, but leaving the rest by the wayside.

As for naval gmes, there seem to be several sub sims, but why not battleship/cruiser/destroyer/carrier? I love running them in the Battlestations games, but those aren’t sims. I don’t want to play a sub. Even in a strategy format instead of first person sim would be great. And not just text missions, make it actually fun to play something more on the serious side.
