While some professional and educational apps may be worth their high price tags, others are just plain ripoffs. Judging by the customer reviews, that seems to be the case for Perfect Penalty 2012. It's a soccer video game that supposedly has the "most realistic graphics," but a review describes it as the "worst game ever."
Water Globe is just a set of interactive screen toys. You can play around with globes and make them snow, change gravity, and snowflake size. We're not sure why anyone would pay almost $300 for this app, when you can probably get a real snow globe for way cheaper.
