Here's mine:
http://www.fantasyadventures.tk
It features a musem of adventure/RPG-games, with front/back scans of game boxes/items/posters etc. in my collection and collector's guides f.ex. from following genres:
Sierra, LucasArts, Tolkien, Ultima, Origin, AD&D (Advanced Dungeons & Dragons), SSI, Indiana Jones, Electronic Arts, Dynamix, Sega Master Systems, Videopac, Finnish games, etc...
Most of the scans shown in the museum are are for PC but also for many various computers/consoles (Amiga, Apple ][, Atari 400/800, Atari ST, BBC, Commodore 64, Laserdisc, Sinclair ZX Spectrum, Vic=20, Intellivision, MSX, Nintendo, Nintendo Gameboy, Philips CD-i, Philips Videopac, Sega Master System, Sega Genesis/Mega Drive/Mega-CD, Soundicvision, Super Nintendo...).
Not that the platform makes any difference for newer Sierra games regarding box scans (~1987->), since the box covers are identical for all systems (except for the platform-sticker).
And the oldest games don't even have PC-versions (most from 1980-83).
