well , few fun maps would be ok but PLEASE stick with default maps for most of the time or have a mapvote atleast.
as for the AMX, having it installed is like a duty but for the love of god don't have it displaying attackers, victims, X terrorists remaining, OMG X KNIFED Y, GRENADE KILL FROM A TO B, 30 seconds until explosion, 20 MINUTES REMAINING, these gay voices and gay display thingies, its just gay and useless and pissing everybody off. also, when you do a good frag and want to make it a movie, you have to hex-edit out all the amx shit before the screen is clear and not full of crap
