As most agree, a GREAT mod... My only 'complaint' is this GOG 5.2 version may have issues if running on newer systems running with some older graphics or hardware. So, I simply pasted 4.0, from elsewhere, to overwrite for this reason. I had the same issue with previous 5.0; worse actually, a year or so ago... I got a blank screen and no load. 5.2 here DOES load, but has serious anomalies in the start menu... arifacts and pixelated; antialiasing may also be broken in-game, on the latest Win 11 but with legacy Nvidia cards.
However, even with this 4.0 'workaround', one doesn't have to install the full game, that has always been a requirement of this mod otherwise. So, I fully RECOMMEND this for download: I also plan to support by soon purchasing dlcs offered here, as this has been a favorite of mine for years, and is VERY well done by the developers: THANKS! :-)
