Hi,
Every indication is that the Steam version works, however you
should ask in the C4 forum for the game to be really sure...;

Be sure to mention your platform/OS/videocard so that folks know
what machine you are using.
Cheers!
Ahoy, the Steam Version does indeed work very well. One glitch with MP games, but other than that it works just fine. I haven't tried the DVD that I got. I looked all over for the expansion, found the thing on sale on Steam a while back, and got em both for less than what amazon was selling just the xp for.
Unfortunately, I don't think that you can just email Valve and get them to authenticate the steam version, but the vendor might be able to do something. But don't hold your breath. I tried doing that with both Star Trek, and EVE, and got told sorry no-can-do. Oh well. For those, the Steam and non Steam version work equally well, so I am not really out that much now am I?
Let me know if you need any help. But as for my tactics --
1)Installed Steam via the CXG Softaware Install tool
2)Installed TQ & TQ:IT
3)Played alot TQ:IT
4)Perused to here to comment :P
So literally the Steam version went VERY well for me.
HTH
