Unfortunately, every game has its own ideas for the best place to store your save files. Steam Cloud makes this simpler to a degree, but it only works with games that support the Steam feature.

The great thing is that Game Save Manager can synch with Dropbox, automatically uploading your game saves to your online Dropbox account, letting you access them at any PC with an internet connection.

GameSave Manager is a Windows freeware that lets you easily back up, save, restore and share your game progress or gamesaves through saved files.
