I'm sure you all despise me by now <img src="smileys/smiley2.gif" border="0" align="middle" /> But know I only play devil's advocate because I care. I have better things to do then criticize products I'm not interested in. Now that that's been said....
Game Maker is $499 for everything that Construct 2 can do and Game Maker is a outdated and somewhat cumbersome environment. I have wasted far more amounts of money on other software development tools. I bought Construct 2 and it is worth every penny if not more.
These features are optional, but the cheapest option is $50, much cheaper than C2. This also has the ability to support exe. However mobile on construct 2 is currently fairly incapable. You do have to pay to catch up to C2's exports so if you're uninterested in exe and mobile that's good. Gamemaker also has a much bigger community, but you don't get such direct access to the devs so tie there. The gm environment seems pretty streamlined to me, the argument could be made either way, after reviewing I see it hasn't changed all too much. What makes you think it's outdated?
I just wanted to agree with what has already been said above. For what you are actually getting for your money, compared to the competition and the outstanding quality and support that Scirra provide, you really cannot get a better product for your money.
Unity provides fully functional support for all platforms, for free. If your interested in mobile, 200$ with game maker or gideros or something for functionality over $120 for a currently crippled system is much better.
The price is not at all steep, as soon as you have a look at the competition.
No it's not, but neither is the competition particularly.
I`m just really thankful that C2 exists and that Ashley and Tom are such great guys.
