I still have the original CD version installed, patched an running on Windows 10 - but this is such an amazing game that I needed to buy it again, immediately, as soon as GOG announced it... both for the cross-platform support, and as yet another way to say "thank you, GOG!" If you have never had the joy of playing this, basically it runs parallel to the original movie - and although the graphics are a little voxelated nowadays, this is very easy to forget as you get immersed in the atmosphere; it genuinely feels like an official part of the movie franchise - the visuals, the voice acting, the soundtrack - all utterly fantastic. Play it through once, learn things, have a fwe surprises and laughs (and yes, a bit of occasional frustration - there are some bits that are timing-critical, so save often). Then when you play through again, try different things - there are many, many different outcomes and sometimes even if you fall back on the same responses you can get different endings depending on sequences of events or the initial RNG. You also have the option of changing the level/tone/aggression of McCoy's responses - or can choose to always be given free choice. Very immersive, fun, deep, intriguing story. Well worth the money. Thank you Westwood for the game in the first place, and thank you GOG for finally managing to bring it to modern systems.
