Many PC gamers use the term "consolitis" to refer to gameplay elements that seem to come from console hardware limitations--sparsely populated hub areas, game environments cut into fractions in order to save on RAM, smaller textures, poor user interfaces, etc. Those that get hatred the most are often console games ported to PC. The most recent example is Crysis 2. Crytek's decision to focus mostly on getting the game on consoles upset a lot of PC users, simply because the series had started and made its name on PC. Crysis 2 was rampant with many design choices made specifically for the console experience, while PC users were left with a port of a sequel that had killed many features that were beloved in the original.
Do I think that console users should not be able to enjoy Crysis? Of course not. Everyone should be able to enjoy games, no exceptions. But at the same time, it's up to the developers to ensure that consumers get appropriate experiences. To those who may game exclusively on consoles, let me try to come up with an appropriate (albeit slightly exaggerated) analogy: imagine that every time a multiplatform game was announced, it was also announced on the Nintendo DS. Now, there's no problem with that, is there? Of course not. Now, imagine that the developer says that they really want to hit the portable gaming audience, and focus almost entirely on the DS version of the game, and then simply port it to the 360/PS3. You'd be furious, right? The game would have been built with touch screen controls in mind, have less than acceptable graphical features, and obviously would not be optimized to take advantage of 360/PS3 hardware.
This is how PC gamers feel. They are disappointed to see games that could be taking full advantage of modern PC hardware being cut back to console hardware limitations, and then simply ported to the PC with no extra work. A recent example of multiplatform release done right was Deus Ex: Human Revolution, in which Eidos outsourced the PC port to ensure that there would be plenty of time to pack in all the features that PC users would expect.
The truth is, PC developers can expect the consumers to upgrade their rigs in order to match the product they are selling, but console developers must downgrade their product to conform to hardware limitations of the console. This isn't a bad thing, it just means that if developers want to win over the PC audience, they need to let PC users know that they care enough to at least try to take advantage of the features of the platform.
