Actually in that situation I would have prefered you A-H party Tofu (provided of course i bring along a slab of beer to make the gaming more interessting. Big parties are fun but they have to be well organised and you have to be sure to have: a) A chillout area with minimalistic music (garage, minimal, pop-rock, etc) at a small volume where people can chat and chill. b) Variety when it comes to the music. You must not have the same style of music on the main dancefloor all night (unless of course it is planned that the party will only consist of that style of music) c) One must make sure to arrange to have a big enough venue so people can move but not too big so that it doesn't look empty. But that Geek party of yours sounded sweet!!!
