Phew, do i have a history with these type of tools.
I pretty much tried every single one, but i'll talk about more recent ones.
I feel nostalgic for Game Maker because my first "Games" were made in it when i was about 9 or 10. but it was shortlived, i loved RPG Maker 2000 and 2003 back in the day.
first time i got serious was much like @Rory when i got involved with the Mirage Source community, Dabbled with the horrors of VB6 with the help of people like DFA, but again nothing ever really turned out of it.
Programming a game from scratch was never my thing,
I was always a mess in everything, especially in code, so i decided to try out Stencyl about 8 months ago, i quite liked it but i had far
too many issues with it, tons of physics bugs and the recent price update really turned me off of it.
Then i found Construct Classic, made a bunch of prototypes and fell in love. Now i moved to C2 and do everything in it.
And hopefully, my first Truely complete game.
