Specially the ones where you have to find stuff.
I usually attempt and manage to get them without looking up any info, but other times I miss something and I don’t want to go thru the tedious process of re-combing whole sections of the levels, or even starting over, just to find some stupid note that I overlooked. Yet, I want the achievement, so I end up looking a guide and I feel like I haven’t truly earned the achievent.
Yes, I know that playing a videogame shouldn’t become a task and that I simply should play it the way I enjoy it the most, but I want too see what others think.
I don’t care, but I also don’t care about achievements outside of it sometimes fascinating me how few people played the game for more than 10 minutes :D
