we most definitely need a failure rate for hatches. I tend to agree with geo's outlook on chances being based on percentage of incubation, but i think maybe there needs to be an added random chance of failure at any percent, except 100%.
people are hatching like mad and pricing creatu, even colored, at 1 tu. Ridiculous. Nothing will ever gain true value again if users are continually allowed to hatch with no penalty. Why bother hatching just to sell at one tu? Save the egg and use it for the egg quest instead. Auction it. Trade it. You have the option to release it, unnamed, also. Use it. names are not the only basis for pricing your creatu. Nattie's have worth also, and so do colors, even colors you don't personally like. Price well, price reasonably, and maybe we can all gradually increase our tu earnings. riyo has a great pricing guide blog; i think the more people stick to that as a guideline, the better res will do.
the only exception to this, should be cs eggs of course. As a previous poster said though, if you can't wait one minute....Well thats pretty sad.
as for seasonals, if you aren't patient enough to wait till 100%, those should fail also.
*flings rotten egg at geo* love that suggestion :)
