One task of the advanced game course is to increase your archery skill. Should your character have above average archery skill already, this is a massive pain in the arse - I have just gone through six bowstrings (so about 600 arrows loosed?) which has taken over two days in game and two hours in real time! T + Enter + Enter, repeat 50 times then go pick up the arrows and repeat, repeat, repeat etc.
It was not fun.
I am aware that the idea is that the player is encouraged to go bow-hunting, and the text for the task makes it seem that you need to be shooting live creatures for it to work. However, some time ago I learned that shooting into the ground or anything really also work; and I am always impatient to get onto the Great Man of the Forest and Kaumo Furs parts of the course, which are great fun.
I think the task should be changed now that making bows is modelled better: Make a bow and some arrows, then hit something that's alive with it. This would still encourage the player to go bow-hunting and teach him how it works, and not leave the players with high archery skill crippled by repetitive strain injuries!
