Sims 3 and LSW3

I'm down to 6 achievements in Sims 3 now. Took a break yesterday though and played some Lego Star Wars 3. Got 4 in that. Amazing how long it takes to finish games sometimes. Especially when you get to a point and it's a grind to finish off. Sometimes I wonder if it's really worth getting all those achievements or not. If I didn't, I could just move on to new games sooner and play through a lot more. Guess being a sucker for completion pulls me in. Even though some games I will just let go as it's not worth it. GOW is one good example.
