I have to agree with Ashley on that one.I have been programming for 10 years now and Construct was the 1st app that really stands out of the crowd when it comes to a user friendly app.And game Maker is actually an app you use for when you want to learn how to program.
Some people i know say that it's "cheating" when i use D&D,But hey you know what , i'm an indie Gamer so that is not even an issue.Even Big games companies use "in house" D&D to create their games.
So paying more for an app that truly is better and more advanced than it's competitor seems only logical.Unless you got 50 grand laying around somewhere to buy a ps3 or xbox360 dev kit.Think about it ,$599.00 for a 10 YEAR licence is a drop in the bucket compared to what you have to pay to go pro.
