its a specific question about these two games, but i guess it might affect other games in the future. at the minute i've a mac mini with a busted dvd drive, but im about to replace it with a mac mini with no drive. theres a couple of games that i want to buy that i could buy to download online, but daftly its far cheaper to pay for a disc and box and postage from uk. football manager 2013. steam euro price 50. amazon uk, 29 pound. starcraft 2. blizzard.com 39 euro. amazon uk, 18 pound. any obvious way of getting both onto my new mini? since the FM 2013 has to be registered on steam anyway to play it, do i have to install it from disc first or can i just type in the retail key and download it? could i install it on another machine and match it to my steam account and then play it? with starcraft can i install the free trial version and use the key from the retail box to register it as the full version?
