yoyoEleanor From what I know, Iconoclasts was started in Construct Classic, but the developer changed engines when he found out that Construct 2 was going Html5-only route. Something similar with the port of "The Next Penelope" for Wii U.
C3 is still relatively "new" so I don'think any "big" game was finished with it, but there are a lot of smaller games: construct.net/en/forum/construct-3/your-construct-3-creations-9
I'm more curios about the customers on the front page: EA, Sega, Zynga, King. What kind of games/products did they made using C3 or is it confidential ?
