Achievements

an article that talks a lot about achievements  within video games and how helpful/annoying they are. there are some good points about some achievements are a small amount of gamer score which you get because your just playing the game like 'kill 5 enemies' kind of thing. i think those kind of achievements have just been added because the game developers were like we need achievements so add some easy ones. recently ive been playing guild wars 2 which has an achievement system where it has some easy ones but they have tier system when getting max tier in that achievement you might earn a title but mostly the player only gains some extra experience and a small amount of money. i think this is a good way of using a achievement system and shows that they have actually thought about what they were/are going to use achievements for.
