I agree but for a day/night cycle to have an actual impact we first need systems like plankton moving up to the surface during the day and moving back to the ocean floor at night, visibility being reduced during the night, etc., otherwise it will just be a pretty cosmetic.2. A day/night cycle which, when coupled with the appropriate genes, would pave the way for more types of interesting behavior. Also, it'd probably be pretty.
3. One of the most important features of any evolution sim is a way to turn off the graphics and just crank the raw processing to the highest speed, to really plow through the generations. I get the feeling with Ecosystem that the graphics aren't really a bottleneck like they were in early alife sims, but 2x time compression is just not fast enough. I want to be able to put the sim into overdrive and let it run all night, to see what comes out on the other end!
I would probably never use this but it would be cool to have an option of just turning all graphics off to let the game run in the background/at higher capacity.
