The purchase went smoothly. I just could pay via credit card, and after a few minutes a download code were shown to me, I could easily print me. After I signed in my Origin account, I have "Redeem Code" under input the code and it was recognized immediately and the game enabled on my account. After the download was complete, the game was installed and I could start it without any problems (on Windows). Even with some 4-year-old extensions there were no problems.
Two things, however, are negative I noticed. First, the download speed was painfully slow. The download of around 6.7 GB took over Ethernet connection around 7 hours a day - comparable Downloads I can, for example, through the App Store much faster load (ca. 2 - 2.5 GB per hour), this was no other way Download, also not in the home network. The other thing was that the game was not running under Mac stable. I needed to bring it 4 attempts to start and liquid it was not very good. If a game is compatible with Mac, it should work.
Tip for Mac users: If you play the game under OS X or even on a Windows partition, I can recommend you a fan-control tool. These are available for free and make sure that your Mac does not overheat. I could play on a Mac mini, Late 2012 without any problem in good graphics quality to play without the Mac was remarkably warm when I was running at approximately 2500 RPM fan. The temperature remained in the range 50-60 ° C (depending on the room temperature).
Otherwise, I highly recommend this game! For the reasonable price worth to revive old childhood memories.
