Last weekend it was Outlore in the South-West of the UK.
For me it was the first time that I participated in it and I must say it was AWESOME. At this moment it's nr2 on my Best Larp List (nr1 is still Dragonbane).
The visual realism was excellent (despite the very visible 'plastic camp') and the atmosphere was magical. Great battles were had along great songs and storytellings by the bards.
I can only say that if you want to try a larp unlike anyother in Belgium you should check out Outlore at http://www.dumnonni.com/ you will not be disappointed.
