What better things can you spend $2.99 on?
Seriously, this game provides a minimum of 4-6 hours of entertainment. Seeing a boring movie (let's face it, most good movies start releasing in May these days...) would cost at least twice that, and would keep you entertained for half that amount of time if you're lucky. I've paid for a lot of apps, but most end up not being used much past the first few days and as a result I feel like I wasted money, not so in this case. It's a great little time-waster when you have nothing else to do and I can tell I'll be using it for months to come. If you actually play through each category of questions, it would take you at least a week to see all the questions packed in here. Most people complaining about repeating questions are probably staying on one category instead of switching it up. I've owned it since the 15th and see occasional repeats, but I'm still seeing new questions as I continue to play.
On top of the entertainment factor, buying now and being one of the first 100 people to steal all of Ben's possessions will get you an diploma autographed by Ben Stein! Shipping alone will probably cost them at least half of the cost of the game, and if they ship it faster then they're actually losing money on the deal for the first 100 people. Add to this the fact that if you are one of those 100 you have the chance to play against Ben, it's a no-brainer.
I look forward to future updates (though I still have to make my way through the content already provided) and look forward to new releases from Griptonite. I had never heard of them prior to this game, but now I think I should seek out some more of their stuff. Great job guys!
