ShinyLoot is a PC, Mac, and Linux game distribution service focused on selling indie games, with minimal to no DRM, and an innovative trait-based approach for users to find new games.
What I find most interesting is their methodology and goal:
Our primary missions is to match gamers to titles based on their interests. In doing so, we want to expand the indie game market horizontally to include lesser known titles.
ShinyLoot recently came out of Beta and is now in full swing, with lots of sales and deals happening, so I recommend checking it out if only for Space Salvager!
