When Stargate is firing on all cylinders, it is hard to beat.
Also, you can run down to an Army surprlus or hunting store, buy a BDU field jacket, pants, and some boots, order a Stargate SGC mission patch online, and you have an authentic Stargate uniform! You can even wear it into Waffle House and nobody will stare at you. Way, way easier than Star Trek, B5, or Star Wars.
You probably haven't noticed this, but a lot of Al Qaeda terrorists in Afghanistan and North Africa (especially Mali) are huge, HUGE Stargate fans, dressing up in Abydos and Chulak costumes even for missions!
