001 is a community supported game creator that remains free though donations that's been in development for quite some time. It is constantly updated, has a friendly community, an easy learning curve, and a complete set of features for creating action / rpgs and platformer games. Features are underway in our beta for point-and-click adventure and 3D games.
The best part is how easy scripting is. Most things are intrinsic, but if you're wanting a big of game logic, this is how you'd go about it:
HUD editing is a breeze, and is quite interactive:
Lighting and fog is simple and pretty:
There's actual depth in games, so making multiple floors is possible:
Character customization is done right within the editing of the map:
Something that seems to be difficult in most makers, is simple - visual character routes:
Particle effects are pretty cool too:
There are plenty of other powerful features...
Sound: playing multiple music tracks at the same time, or placing speaker objects to have sounds positional/3D, with support for plenty of audio formats
Graphics: full support for alpha-blending and soft edges
Collections/Tables: these allow you to store data in very simple ways
Custom Events: allow you to create your own events that you can call from everywhere else, while also customizing what options they'll have
Input Sets: you can easily switch between input sets, which are powerful ways to customize key combinations if you're doing a fighting game for example
The web-site offers many features too...
Games: upload and download games without worry of viruses (as EXEs aren't actually being transferred)
Resources: resources can be shared among users easily, with auto-generated previews and rating system
Tutorials: user-created tutorials about almost any topic, with ratings and search
