Steam Cloud is a feature of the Steam client that allows save game data to synced to the cloud. A list of Steam Cloud games can be searched for on Steam, though some games are not listed there even though they use Steam Cloud.
Steam Cloud implementation is very inconsistent among developers. Some choose to only sync configuration files, some force users to choose only a single slot to be synced. Some games list Steam Cloud as a feature, but do not sync any data whatsoever. Some examples of such games are Halo: Spartan Assault and Capsized.
Steam does not scale DPI properly over 100% DPI scale. Valve has still not implemented support for HiDPI resolutions.

While the current Steam package already includes required libraries to work, they are sadly outdated as they are from Ubuntu 12.04. However, Valve included an option to force Steam to use the libraries used in your system, also known as Steam Native mode. This can be done by adding STEAM_RUNTIME=0 before the command for launching Steam.
It's best to create a separate executable file for it in order to allow easily switch between the Runtime and Native.
sudo nano steam-native
# Workaround for dbus fatal termination related coredumps (SIGABRT)
# Override some libraries as these are what games linked against.
exec /usr/lib/steam/steam "$@"
sudo chmod +x steam-native
Once done, you will be able to run Steam Native with the steam-native command on Terminal, you can add it to the Start/Program Menu if you wish, but it is also best to add it's .desktop file as well, so it'd be available and automatically added.
sudo nano steam-native.desktop
ArchLinux based distributions only require installing steam-native-runtime package which will automatically install required repositories and automatically set everything for you, once you install Steam.

Steam is famous for having long periods of deep discounts which apply to virtually its entire catalogue of games. During this period, Steam will usually run daily discounts, further slashing prices (as low as 90% off). Therefore, it is a good idea to hold off buying a particular game unless the game is on a daily deal (or flash sale), or it is the last day of the sale.
During Steam sales, you can make sure you are getting the best price available by using a service like IsThereAnyDeal, CheapShark or SteamPrices, which compares pricing across multiple game stores/distributors/regions.
