Terragenesis

I have mentioned this game before I think. It is terraforming, pretending to transform other moons and planets to be habitable. It's one of my favourite games, and the biosphere option is (very hard but) fun to play. Only I thought just now while looking at the ecosystems, is this wrong? In the description for a basic terrestrial species (building thing) is says the first part is designing a species. That's why I did not want to work in genetics even though genetics was my favourite unit of freshman biology, the designer children concept. People paying to have "perfect" children engineered for them. It seems creepy and unnatural and weird to me. I personally do not like the idea of people altering genes like that and even trying to create some things people say have been tried or may be tried So back to the game, I mean we can't create life. Is it wrong to do this in a video game? Adding species? There is a way to play with "biomass" instead which uses already familiar species but,

To give an example, here's how it works:

If I want right now more plant species would be good. I'll go for a grass, +50% birthrate and -25% support required (they need less of the previous microorganism level to expand). And I go into genes with ATA --- --- ---. I pick three genes and get a sequence like my bush I have already is ATATGTGCGCGACTC (it's hard to copy this might be wrong but you get the idea). It's a shrub, with genes "beautiful", "fruit-bearing", and "cash crop".

Advice? Is it okay to play biospheres or only biomass?
