It's not like that - while yes, Construct is open source and MMF costs money, these are facts - you present them as a strong opinion (ie. nothing can possibly be better than Construct, etc). This is not realistic. MMF is mature software, so has fewer bugs, and a larger userbase, and a few other things like more plugins - all positive points. I'm flattered by your passion for Construct, but you must keep perspective - remember, I would still advise someone working on a commercial or otherwise important project to use mature software, be it MMF, GameMaker, or waiting until 1.0 comes around. Until then, Construct still might nuke your file or make it 3.2 gigabytes, heh.
So the point is, while I'm not asking to control your activities on the internet, I'm urging everyone to keep a realistic view, don't lose your heads, and hey, it's only an internet rating. Rate it 5 stars since they seem to take it so seriously
