I have no problem with that generally because I would rather see downvotes than see every single person who disagrees feel compelled to pile on with petty BS. But in this case, the comment called attention to a defect in my earlier comment -- my failure to specify which SimCity -- and allowed me to add the missing information.
Since my reply with the additional info has substantial upvotes, I think it's wrong to punish the comment that elicited that reply from me. It has too much of that "you win an argument by making the other guy lose" vibe.
I hesitate to say this explicitly, because past experience suggests it will result in a temporary pile-on of everyone and their brother nitpicking the hell out of my comments, but I really don't want to discourage good faith comments that nudge me to address defects or omissions in my comments. I don't think that improves discussion here. I think it makes things worse.

Also simcity 4 isn't meant to be a 1:1 mapping from game to real city anyway. Most buildings in simcity4 can hold a multiple of what they would contain in real life; it is a model of a city, not a real city, after all. So it stands to reason that they could just cut out the parking lots for aesthetic purposes.
