And the multiplatformity won!
I’ve been playing the Ludum Dare games and I feel happy that the majority of the games was made with multiplatform tools.
I’m a Linux user and it’s horrible when the games have versions only to commercial OSs. Linux is the choice if you don’t like to be owned by some huge corporation. And under Linux you are free from the CIA spies 
Many Unity developers are exporting the games to Linux and it’s working very well. And web/javascript games are naturally multiplatform.
I see a paradigm shift here. Now we have a world where monoplatform development is not acceptable anymore.
P.S. – Play my (multiplatform) puzzle game entry!

SDL 1.2 with many aux libraries
sfml
DirectX 8-9
Game Maker 5-7
Anything using WinMM/GDI
C# 4.0 with heavy use of the Windows API (In conjunction with mono)
To all those people using bleeding edge technology: Screw you guys!
