Which game was the last one, which totally did cut you from your enviroment, i mean, you don't see anymore the screen, you don't hear anything which happens arround you, a earthquake could happen an you wouldn't recognize it.
I bought 2 days ago Mass Effect 2, just to bridge the time until Fallout Las Vegas will be released, since i am a absolute Fallout-Fan.
I must say i am a strong smoker, up to 2 boxes a day (yes I failed stop smoking), but yesterday i started Mass Effect 2, created the char, gone smoke a cig, and totally forgott time.
