Interestingly both dune and dune 2 were released around the same time and both are amazing. Dune 2 created the rts genre while Dune was a wonderful combination of adventure and strategy.

For Dune, I'd recommend the CD version https://www.freegameempire.com/games/Dune-CD

There's a great series of articles on Filfre about both games and the Dune universe https://www.filfre.net/2018/11/controlling-the-spice-part-1-...
