I'm usually heading to GG.Deals to find new games and best prices but there's a feature missing that exists in the Steam store and also the Steam Database webpage. That's the ability to prune search results based on tags. With Steam database (for a while now) and Steam you can EXCLUDE games based on tags (e.g. +OpenWorld +RPG -MMO). You can't do that with GG.Deals right now. It would be a huge feature to add.
