Completionist game padding. What I call Easter Egg Hunting in game. I can't stand games that forcibly insert random stuff for you to go and collect, for no real reason other than to collect them and get an achievement. The flags in Assassin's Creed 1 for example. Totally pointless, and annoying. I get that the game devs want you to explore the fun cool world they spent months/years creating, but really why should I stick my nose into EVERY freaking corner and house and closet in the game, looking for useless trinkets that aren't there for any purpose? Busywork annoys me to no end in video games.
For me the inFamous games did this thing in the best manner. The shards you were collecting had an in-game reason for being scattered everywhere, you had an in-game method to help you find them (the pulse radar thingy to locate nearby ones), and there was a practical reason for doing it. (it increased your power pool for using your abilities). THAT kind of Easter Egg Hunting is tolerable to me, when it makes sense to the story of the game, and isn't some kind of Metagaming , pokemon-esque "gotta Achieve em all!!" bullshit.
