Steam still won't keep the rogue title up-to-date or save your game to Steam Cloud, but adding non-Steam games to your library lets your friends see when you're playing the game, and unlocks the Steam overlay feature (Shift + Tab) including full screenshot and in-game chat functionality.
Got it? Good. Now open the Steam client and head to Games > Add a Non-Steam Game to My Library. The process is straightforward from there. If you want to add a custom image for the game in your Library's grid view, just right-click on it and select Set Custom Image, then go from there. The fine folks in r/steamgrid on Reddit will whip up custom images for games if you'd like. You can find a ton of custom grid images on the Steam Banners website or Deviant Art, as well.
Power-up with Enhanced Steam
The powerful (and free!) Enhanced Steam browser extension might just convince you to start shopping on the Steam website rather than within the Steam client itself. Enhanced Steam packs a multitude of handy-dandy features designed to help you know when to buy--or not buy--a particular game. It'll show you when a game is already in your library or wish lists, show the pricing history for individual titles, reveal just how much money you'll save in a games bundle, and heck, even sniff out games with third-party DRM.
And that's just the beginning. Seriously; if you're a PC gamer, there's no reason not to go install Enhanced Steam right now.
Manage where your games land
Maybe you want to shift all your titles onto a blazing fast SSD, or maybe you installed a spacious new traditional hard drive that's just begging to be filled with gaming goodness. Either way, Steam makes it a cinch to add new folders in which to store your games.
Open Steam and head to Steam > Settings > Downloads, then click the Steam Library Folders button. From here, you can add as many folders for game installations as you'd like. Once you've added additional folders, you'll be given a "Choose location for installation" option when you're installing a new game. Easy-peasy.
Moving already installed games is much trickier and involves the use of symbolic links, which essentially trick your PC into thinking the file it's looking for is still in its original location after you've moved it. We explain the manual way to create symlinks in PCWorld's guide to proper SSD management, but you'd be better off just using the incredible Steam Mover software. No, really--just go download that and follow the instructions. It's way easier than the DIY method.
