Played all versions of D&D & AD&D and my current game group settled on 4th ed by default when we started up again a few years back. To be honest the game system is irrelevant to us - its just an excuse to get together every 3 weeks and take the piss out of each other, have a laugh and an enjoyable evening. Having a "game" to play just makes the social aspect more regular, otherwise there would always be some reason to miss this get together...
We've taken a rest form D&D lately and are currently playing a Chill-based modern horror (think Charles Stoss Laundry...)
