I am not 100% sure which other modes I will implement but laboratory is on the top of my list. I am happy just to see what evolves but I suspect only a small fraction of people are like me and just want to see what happens. Anything that 'gamifies' the simulation and makes it more fun is ok with me.(really I just want to keep people running the game to create new creatures) A laboratory would give you a window into their DNA and see how they tick. I could let the player tweak the dna to see what happens or put it through a tumbler to get 100 variations then have those fight it out? Really not sure, its a tough first project to get traction on tbh.
I am still toying with the miniaturized ship idea to make an actual game where the enemies keep getting harder to beat. You could play against creatures by level and if they kill a player they level up. The odd thing is I don't know what would happen, it may keep getting harder forever, become impossible, or level off in a month/year/? It was a very ambitious project to start with and I cant even begin to describe how complex it was to set up a dna system that procedurally generates such a variety of creatures with virtually unlimited behaviors. There are somewhere around 2^8000 combinations, I think that number has about 2500 zeros after it, give or take a Googol or two.
