I dunno. I see lots of complaining about all games in general, I've never really noticed from serious and intelligent gamers complaining about games because they are popular.
I HAVE seen people complain about games changing to appease the masses BECAUSE they became popular, like the Elder Scrolls. But that's not complaining that the games are popular, that's complaining that the games have essentially "sold out" by changing features to make it more accessible to people who barely play video games, when it's a gaming franchise that was built off of hardcoe gamers.
I myself am one of these people that have complained a lot about the direction of the Elder Scrolls franchise, but i don't care whether it's popular or not, I care if it's a good game that takes time on the details. I do however attribute some of the design choices in the franchise to the fact that the games became popular and bethesda wants to keep that going and try to grow its fan base. But i dont necessarily think that the elder scrolls being popular is bad by any means, I think they just acted on it wrong.
This is sort of an obscure anology that many people wouldnt get, but it's sort of like the band Megadeth when they released their album "Cryptic Writings" which was more of a pop type of sound then their classic Metal, but it sold a lot and was still a pretty solid Album. Then their next album, Risk, they decided that since their more mainstream pop kind of sound worked last time, they decided to try it again, but more so. The result was that Risk is probably Megadeth's worst studio album ever to be released and outraged many fans, not because it was popular, but because they changed the sound of what we knew and loved about Megadeth into a crappy Pop rock sound that was a blatant attempt at being more "radio friendly".
I don't think the fans were being elitist and smug when they said that the album svcked, i think it was because that's not the sound that got the fans into megadeth in the first place.
Just like i dont think the Elder scrolls fans are being elitist or smug when they say that Skyrim svcked (for a TES game), or that they don't like the general direction TES games are going, because what got lots of us into TES was the hardcoe RPG style and not the mainstream hack n slash that it seems they're trying to aim towards.
All that aside, I'm probably somewhere in the hardcoe gaming community I guess, but i don't have any aversion to playing games like The Sims, and actually don't mind the sims at all. It is what it is. Now if the next Elder Scrolls or Fallout game that came out was a Sims clone with different makeup, then yes, I would be extremely pissed because they just ruined a franchise to try and capitalize on the Sims customers, rather then make an entirely new game for those kinds of people (if wanna do that, then go ahead, just don't ruin a perfectly good franchise because of it).
