Me too I like gardening so much and I am actually happy that now your plants won't die unless you really neglect it. I like the idea of the sims 2 greenhouse but i feel like it just a place where I can produce all seasons and nothing more. In sims 3, I like the fact that they add a better fertilizer machine and that the garden always seems to grow faster inside greenhouse. My complaint is they are not included in Seasons at all, and having PvZ sunflower is very annoying since it spam suns without option to turn it off.
I would like greenhouse to be integrated like in TS2 Seasons but have more benefits like in sims 3. And I hope for people who didn't buy yet, they would at least release free sprinkler. And I would prefer super green thumb to naturalist as reward for completing freelance botanist since it makes a lot more sense.
