I haven't had any luck with Close Combat: Cross of Iron (which I think is the better game), but I installed Modern Tactics with no problems. Here's what I did:
- Created an XP bottle.
- Installed Modern Tactics from the digital copy I bought through Matrix Games.
- Patched Modern Tactics to v.2007.12.121, which can be found on their website.
- Emulated a virtual desktop from within the graphics tab of winecfg. Without this, the game loaded and made sounds, but it refused to show visuals.
I haven't played more than a few minutes of the game, so I can't attest to its stability. However, I can assure you that it loads and runs smoothly on my 2008 iMac.
