I've been playing the Sims 3, which has been out for quite awhile now. There are several expansion packs for it. It is an extremely popular PC franchise with a large rabid community. Despite all that, the game is still buggy.
My first playthrough featured a loss of two hours when I hit "Error Code 16". Basically you can't save your game. Game save bugs are amongst the worst types of bugs.
I have a pet fireman. One of my Sims wanted to "be in a fire". So I had him start grilling some hot dogs and then sit down nearby to play some chess. Cue fire and ridiculous Sims jumping around. The Fireman shows up in a little red firepickuptruck and puts out the fire. Then he stands there. You can't interact with him. I thought he was stuck on the grill that burned, but I moved that out of the way. Even once in awhile he will stumble and look sheepish.
One day while a Sim was watching TV I randomly clicked on the fireman. "Join: Watch TV" was there! I clicked and the fireman moved! Hooray! Problem solved. Except now he is permanently on my couch. That was worse, so I used the same technique to move him back out to the lawn. You can't talk to him, but he will join you in activities.
Having a pet fireman is fine. There's always a chess opponent nearby. He never seems to get hungry/dirty. However, his truck is a problem. First, the garish light is always on. Luckily, no sounds. The big problem is that it blocks the street. Any time a car comes to pick someone up they park really far away.
Anyway, you'd think they'd fix this stuff after several expansions. Actually, the Word Adventures expansion apparently created the "Error Code 16" problem, even for players who didn't buy the expansion.
