That's quite a lot of views in a short period of time. I never realized something as boring as house plant simulation would interest so many people. Having said that there are many boring games out there people seem to buy such as farming simulator etc. Some peoples minds seem to be stimulated by very little.
So as Lee says in his blog someone should look at actually developing house plant simulator. Maybe the addition of a watering can so you can make plants grow. Some strategy element so you can buy/sell plants at different stages of development might be a good feature. Obviously you could get pests in the form of bunnies who you have to keep away from your precious plants. You might also have destroy some of your plants or they might have a disease which spreads to other plants... the worlds your oyster then it comes to house plant simulation and GameGuru!
