It depends on who you're talking about. There are many different types of gamers out there. The biggest violator of this is what I'd call the `en masse` gamers - Those that play only the most marketed titles that 'all their friends' are playing. 95% of their library include games like CoD/Modern Warfare, League of Legends, and Diablo III.
The second violators of this are what I'd call the `On-the-Go` gamers - People who play games that don't take a ton of involvement or time to get going into them. Their library typically includes games like Angry Birds, Bejeweled, Sim City, and Nintendoland.
Coincidentally, it seems to be that the biggest names out there seem to focus their marketing on these two archetypes the most. I partially think it is because they're the least interested in all the crap and drama that goes on in the games industry, and secondly, they're the most impressionable when it comes to marketing. Make things big, gritty, and loud to attract `en masse` gamers - Make things colorful, shiny, and quick for `On-the-Go` gamers. Easy money.
It is quite a bit more difficult to reach the `core` gamers (of which there are many sub-types). These people care less about games being easy to consume, and more about the quality and depth of a title. These gamers have no problem with voting with their dollar and will often prefer games they know and love if the newest game doesn't look up to par. Unfortunately these types have been slowly getting outnumbered as easy to consume games bring in new customers that don't really care about the differences between developers or publishers.
Regular gamers can be great customers, but slowly it seems like games are being marketed toward gamers who don't care about the games they're consuming and who won't complain when 50kg of DRM and ads are tacked onto their game.
