Now that I am more familiar with Donald Duck’s Playground, I can tell you my honest personal opinion about it. In short: it is the worst game I have ever played, not less because it is supposed to be an educational game for children. The only thing it does is to teach your children to become the worst kind of brainless consumer robots on planet Earth by insisting the player to iterate through the most dull game mechanics I have seen, that is, by having Donald Duck to work odd jobs to earn money in order to buy uninteresting toys from a few stores for his nephews. The only good thing about this game is that the player cannot die in it, unlike many other Sierra games where the player infamously dies around every corner unless you magically know the exact sequence of correct steps to proceed.
If my job here was to redesign the game the first thing I would change would be to make Donald have to take his nephews, along with a few bottles of milk prepared by their loving mother, and make an idyllic trip to local landfill to collect useful items from the dump. These items would then be brought to Gyro Gearloose who would help the nephews in building a space rocket out of the recycled parts. The rocket would then be launched to space in order to go teach manners to three-headed negro monkeys of developing planets.
Those items from the dump that couldn’t be used for building the rocket could be used for positive terrorism and thrown against the windows of the now-useless stores. Maybe it would be even better if the stores were replaced by only one store with coffee and alcohol in millions of kinds of bottles and packages. Special coupons for use in this store would then be distributed for everybody, and the actual use of these coupons would be closely observed by all goodwilling, respectable citizens, and if even one unused coupon was found the co-citizen in question would have to face a year-long correction camp for his own good. Yeah, the nephews, being technologically advanced citizens, could use the extracted alcohol as fuel for their space rocket.
