Will Breedtown 3 have exactly the same mechanics as the last two or will it differ slightly (I am completely ok with what you have currently, it is a masterpiece)
Not exactly the same, no, BreedTown 3 is going to play pretty differently from the previous 2. I'm glad you liked this one, but I received some complaints about various things in 2 (map structure, re-breeding, etc.) so I want to experiment with different stuff and see what people do and don't enjoy.
