Ok, note to the admins: There isn't really anywhere else for this...we need a general section (As in actual bit to post in as 'general')
IRL (In real life) creatures are effected by a lot of things, pressure etc. Temperature, salts & chemicals are just some, and it would add a new level of complexity in my opinion to bot survival, if there was this...It'd also improve waste because currently waste is just...toxic nobody knows stuff...But IRL its build-ups of bad things inside an organism, and these are from intake of materials & doing things so what if we had a list of maybe 10 chemicals, 3 salts and then temperature, bots metabolism etc. may be effected by temperature, they may expend more energy in certain temperatures, and may be cold blooded (uses less energy but of course, most unstable) or hot blooded (using more energy) and the fact that these factors wouldn't be equally distributed (and tick-boxes can show a overlay onto screen of these...so red might be, hot/high concentration of X and blue be opposite). This would put bots on more equal ground...So the spectacular hunters, might start to really struggle in non-temperate enviroments, giving under-dogs an advantages...Like IRL.
A lot to getting DNA and genes to work right, is down to whats around you, if chemicals and temperature didn't exist, we would be much simpler beings than we are today.
