It’s so weird that elves are now the good guys. They were actually dream spirits that give you nightmares (engl. nightmare ≫ german Alptraum = elf dream). And no, they weren’t described having otherworldly beauty.
It’s also believed that nordic elves and dwarfs are the same beings in the Edda. The nordic word for elf is álfr which often is part of dwarf names.
There’s mostly only some really funny voice over during the missions. EDF6 is already there but the developer always takes his time to translate the game into English.
If the game loop doesn’t run at the same speed as the render loop you’ll get ‘tearing’ - some game objects are at the latest state, some are not. That can cause some funky bugs.
Because it’s easier to programm a single thread that executes a sequence of commands like [ update-gamelogic, update-graphics, etc. ] instead of at least 2 threads (for gamelogic and graphics) that you have to synchronize somehow. Synchronization can be pretty difficult!
