First off I would have to say that this is one of the most enjoyable games I have ever come across, and I thought that about Fish Tycoon too! I have even quit playing WOW and GW for PT. I am a notes and spreadsheet person too, just like lp7p, and I am enjoying the waiting to see the little sprouts. However, for those who are not notes and spreadsheet people, it would be easiest to have a listing with ??? marks that fill in once you've bred the plant, as well as a genealogy tab to see the parents and grandparents. Another thing I completely agree with is the magnifying glass to see your plants, I've completely junked a grass plant just to get to the three little grey hairs at the very back of the plant. And of course, MORE greenhouses!
An idea for PT2 of my very own, so far, and that is, Tadaa, having a great game. And since it Might be made by LDW, I know my idea will be in there. Have a Great Day!!
