FM2015 Installer of Steam Version

Should I redownload the FM2015 from Steam if I move to a new computer, or, I can save the FM2015 installer into my hard drive without have to redownload whole game from Steam?

My internet connection is slow, the size of FM2015 is more than 1GB, it will consume much amount of time if I should redownload the whole game from Steam.

There are parts of the game that can only be downloaded through steam, so I would suggest that the cleanest way would be to download steam onto the new computer, access your steam account and download the game from scratch.

This.

I'd suggest just downloading via Steam and leaving it alone while you do something else; start the download right before bed or before work or before you're about to hang out with a friend, etc.

Go into steam, backup your game, move the backup to the new computer on a USB, install steam on the new pc, restore the backup via steam, play the game.

Or save your save-games to Steam...

This is what I would suggest. I do a similar thing for moving games from my SSD and regular HDD.

Indeed... backing it up onto a usb/dvd or whatever is the quickest easiest way.

i.e right click the fm15 shortcut in steam and you'll see the option to backup there.
