A fully working game is not a game where you can't change resolution and controls using the built-in utils (modifying and xml file is NOT a user friendly way) or a where all models heads disappear after the very first launch. So no, SWTFU engine is not working well with wine and the fact SWTFU2 is crashing specifically when you try to load a level (init the engine) is another proof that engine is buggy with wine. Now let's hope wine devs will be able to fix SWTFU engine bugs, considering their talents it will no be long i'm sure :D
