Dazeland!
Amiga-centric site in French and English language.
Whole continents about 3D shooters and Adventure games.
Huge site, mainly in Spanish, but vast parts are bilingual. The design can be a bit confusing at times. The strong side is certainly that it covers different versions for many different systems, so there's a lot variety!
Website dedicated to the Space Quest series by Sierra. The meeting place for fans!
The #1 place to get help for the games you downloaded from here!
Huge archive of scans of old (German) computer magazines!
Extensive solutions and guides about semi-old games.
WinWorld
Collection of properly preserved software (mainly applications).
