Simple ideas are great. However, many of these ideas are easier to come by if you have experience in thinking up such ideas. Still, it often takes some time weeding out bad ideas until you find something which will be fun, playable... etc.
I read through the first couple of pages and ignoring the rest( sorry ) i have to say it doesn't really take time and experience to make a good game. You just have to make a game that people want to play, and it can be the most simplistic idea ever for a game yet become instantly popular.
Once you've got an interesting idea, it will still take some effort for it to be successful, while your post seemed to imply that not even the slightest effort is necessary. If that were the case, YoYo Games would be flooded with only good games.
