Two I’e been thinking of two for a while -
I’d like something along the lines of the Sim series called Evolution. Maybe based on the Discovery channel series “Walking with Prehistoric Beasts” and the other one they did on future evolution.
Where you start with a species of animal, and in reaction to competiion and climatic changes you make choices, but not menu choices, just in the way you play the game, like if you have to get food, and you find it easier to find food in the water, oer time your species begins to evolve into an aquatic mammel. Basically your choices are made based on how you play the game, so your creature adapts to a specific type of behaviour.
Hopefully also, there would be enough variables so you would never wind up with the same final creature twice. You could set series of starting points, like mammal, reptile, amphibian, etc. but each and every one of your actions over the course of the game would alter your creature’s appearance and abilities. You’d make decision on how you get food, how you protect yourself, how you reproduce, etc., and these decisions would cause your creature to evolve.
I’d also like something like maybe Tropico, but with Sims-like character interaction and openendedness. Where you either play as a Dicator and you have to wield together coalitons of industialists, labor, military, church, social groups, foreign agents, etc just to remain in power. Or the flip side of this, where you play maybe an insurgent tryign to topal a government. This game would have to have a Fallout-like moral compass, only more so. Everything should be possible, a true Adults Only game. The world would react to your actions, and characters would change over time, like maybe the Archbishop of the chuch you have spent 20 years cozying up to dies, and is replaced from Rome, by a young idealist preist who supports worker rights, and you have to decide how to deal wiht this. Have him assasinated?, change your ways?, ignore him and try to form a new coalition?, etc. PLus, I woudl like it to be kind of realpolitik, for example, the US wouldn’t be represented as the good guys and the Soviets as the bad guys as in Tropico (though it does to its credit tweak that a little), but everyone should be portrayed as self-motivated players out for themselves, and willing to lie, steal, cheat, kill to get it.
