I run in to the Problem of not starting at all because of having more than 8 cores There is a fix for it https://github.com/adrian-lebioda/SpaceMarineCoreFix Found it via Steam https://steamcommunity.com/sharedfiles/filedetails/?id=2023164262 But if I buy it on GOG i expect the fix be part of the game. (keeping old games alive???) Then I also needed to run the game with admin rights. --> 1 Star removed The Game itself is a 4/5, simple solid story. Hast a lot of fun parts, slashing orks and later chaos, i don't like it if you can't jump at all and the limitations of only 4 weapons would have loved to rotate through the whole arsenal.
