Renoise (PC/Mac/Linux, 00's, “free”)
Music (Schism Tracker) 2/4
GPL license
Written in SDL (works for many OS's)
Supports MANY module formats
Familiar interface (Impulse/Scream Tracker)
Tracker format (Module)
Sounds exactly the same on all players

SDL (“standard” libraries) 2/3
SDL (~300 kb)
Main library (BMP, WAV, etc.)
SDL_mixer (~150 kb + mikmod(~200kb) + etc.)
MP3/OGG, modules, MIDI (software wavetable)
SDL_image (~40kB + jpeg(~100kB) + etc.)
JPG, GIF, PNG etc.
SDL_ttf (~20 kB)
TrueType font support
SDL (examples) 3/3
Game engines
ScummVM, DOSBox, ZSNES, etc.
Games
OpenTTD, Frozen Bubble, World of Goo, etc.
Games (Linux only)
Doom 3, Sim City 3000, etc.
Eggerland (Title screen) 1/7
Eggerland (In-game) 2/7
Eggerland (Environment) 3/7- Mountain
- Winter
- Beach
Eggerland (Water) 4/7Perlin Noise
Using 2 octaves
Very realistic!
Eggerland (Editor) 5/7Using Qt
+ Fast and easy to develop tools
+ Easy to read/write data (QDataStream)
- Qt is large in file size
Eggerland (Editor music) 6/7
Using SDL_mixer with mikmod
Using XML to store misc data
Eggerland (Demo) 7/7
