I would definitely choose limited features. That was one of the reasons why I asked my parents for Virtual Villagers. I really love that you can sorta play the game, but then you have to buy it to get further. I don't really mind the 60 min trial one because most games are like that, but it does get annoying when you're playing the game and then it suddenly stops, and you can't show it to your parents when you ask for it.

And I wouldn't choose the other options because the ads in between levels one is really easy to ignore and I am pretty sure sales would go down drastically, buying items with real money would be really weird, not to mention annoying (like in Club Penguin when you can't buy many items without a membership ) and the other option was really confusing for me
