comicbookguy90: So first thing is for me to download game on Galaxy and move to a different storage spot? If im no longer using galaxy just make sure to install every new patch?
You can just download the off-line installers and files (your need all 4 parts) and then double-click on 1 of 4 which will install the complete game without Galaxy.
Galaxy is not required unless you wish to have access to multiplayer and the full quicksilver shop or perform the community missions (daily and weekly). You also cannot get the additional credit for uploading discoveries.
If you install Galaxy and even download the game through Galaxy you do not have to play within Galaxy. You can launch just from the No Man's Sky link but you will not have access to the gameplay options listed above.
When the next set of patches are released you can either use Galaxy or simply download the patch and follow their instructions to install (basically just launch that downloaded file).
Good Luck
