Some Steam guides (of mine) of interest:
- Developers, fix your volume sliders! - cause they don't respond right at all.
- About FOV (field of view) in computer games - you think you know, but you probably don't.
- My "low FieldOfView = thumbs down" policy - no matter how good the game otherwise.
- Compendium for the perfectionist game developer - in case you want to make a difference.
Instead of Steam's shallow category system, it has user-defined tags (which can be categorized :P) and even allows to rename games. The feature list is rather long, and you should check it out if you prefer several game clients serving you instead of you juggling several game clients. Just forget if a game was on Steam or GOG or Uplay or manually installed - just manage it all with one powerful front-end.
Btw., you can navigate to a game's PCGW page directly from SlaloM!
It was December 2013 in my Steam Library when it didn't yet have multi-select, and I had reached about 400 games, when I decided to write my own game library manager (SlaloM - see screenshot). Two weeks later, I was managing (and launching) my Steam games with tags and could even rename them. It's how I have been gaming since. I have no idea how people with several thousand games live without a manager like SlaloM. I've reached almost 2200 games, and I keep finding new ways of exploring the depth of my library (manager).
Here's what it looks like in action: https://www.youtube.com/watch?v=G6ffpXkg648
By now, the feature list is extensive, e.g. you can define root folders from which SlaloM will automatically add games to its library, so whenever you manually install new games (Or applications, it really doesn't matter.) or do so with any other game client, SlaloM will have the games in its library on next start. It can even download your Steam game purchase info via browser automation (and can then export it as CSV), allowing you to sort by how much you spent for a game, how much it was discounted, etc., and you can even sort by installation drive/path, installation size, amount of screenshots, ...
Basically, if you desire even a mundane feature like showing a random screenshot when selecting a game from the library (changing on space bar, going fullscreen on hover, with slideshow feature and favoriting), take a look at SlaloM. No install required (except Java 8): Just make a folder, drop the <1MB download in, run it, and immediately see your Steam games with their local screenshots, you can browse your current filter results in the form of screenshot tiles from which you can directly switch to seeing all of a game's screenshots in chronological order, you can of course run them, etc.
SlaloM's main problem is that it isn't known, and your main gaming-problem may be that you haven't tried it yet! You may not expect a revelation, but you may well find one, so you should take a look. And spread the word! Millions of Steam users have no idea that there is an answer to their needs, one that billion-dollar company Valve for some reason refuses to give.
