With the Sims, they make you buy 'simpoints' before you can buy anything and then charge simpoints for the items, putting a deliberate layer of obfuscation between the user and how much they're spending on each item. It's deeply fucking cynical and since the monetisation strategy will all be planned out during development, you are going to be missing things from your game that would have been put in otherwise, as well as seeing lots of customisation bling stuff that in the past would have been put in as polish, but now you'll have to pay for.
