Paint programs
To draw your own sprites, animations, etc. for AGS then you'll need a painting program. Windows comes with Paint, of course, but that isn't bristling with features and you may find things like layers, animation, filters, etc. would be useful. So here are some alternates:
Professional level
- Photoshop (Commercial)
- Paintshop Pro (Commercial)
- GIMP (Free)
Pixel art and sprite oriented
- Graphics Gale (License?)
- Pro Motion (License?)
- Grafx2 (License?)
Other
- Paint.NET (License?)
- ImageForge (License?)
- Ultimate Paint (License?)
- Photo Filtre (License?)
