There's always going to be bugs. Every game I play has bugs and every forum in every game I play discusses this same situation. Let's say they did take a year off to fix the bugs. They come out with new content and who's to say that those bugs plus new ones aren't going to just pop right back up? They should at least try right? They can do both. Work on bugs and release new stuff. There's always going to be bugs. Maybe I don't have as many bugs as others have or maybe the mods I use fix them, or I don't play as much as others idk. The only bug to me that's annoying that I don't believe they know how to fix is the restaurant taking a whole day to visit and the sims not sitting down to eat.
New content > bug fixing. I see a lot more complaining in these forums about the game needing more content than I do about bug fixes.
