Weird, because it's labeled DRM free and the reviews say it's DRM free... If you're correct, then I appreciate the heads up!
Edit: Ah, here it is: "Note: If you already own X Superbox and redeem the game on Steam you will get the X3: Albion Prelude Expansion Pack for Free." It'd still be worth it to me to purchase that version to get the other games DRM free.
Psst... If you download X games in Steam, go to egosoft site, download the latest patches, ignore their installer complaints and force them into the corresponding game folders... you'll get your sweet DRM-free. Except AP, the devs keep it steamed and don't release patches outside of it.
So, I did this and you were right! I really appreciate it, you saved me some moneys! It seems as though X3:TC still works, but it's possible that I'll encounter some issues in the game since the patcher that makes it DRM free downgrades the executable from 3.2c to 3.2 (it was updated Nov 27th of this year to 3.2c in case you were unaware of it), but the game does load up just fine. Hopefully one day they'll release a similar patch for AP. Thanks again!
