I have a question.I bought retail czech Witcher EE. I installed it, applied hotfix and walk-mod.The game (supposedly 1.4?) now works without dvd - it runs without dvd in drive, and I tried tutorial and also without problems.So....is this normal? Because I read that retail versions still had disc check, PLUS 1.5 should get us rid of disc check - but why, when it already works without dvd in drive? I just do not get it.Can anyone clearly explain to me what is the deal with disc checks in all the versions and why my retail EE works without dvd in drive?
