There sure has been a lot of hoopla over the PS3s lack of rumble. Gamers everywhere are decrying how this missing feature will make games less immersive and enjoyable. But yet, when it comes to gaming, there is a double standard between what is expected on a portable versus that of a console. There have been many generations of portables since the rumble feature was first introduced to gaming and yet, it has yet to be a standard feature on any handheld, it has just been built into a few game cartridges. Wouldn't that portable first-person shooter or driving game benefit from the inclusion of force feedback? The DS has a built in microphone and the PSP can browse the web, but neither have a feature that is standard on nearly every console for over two generations.
Sure, some would argue that they don't need yet another feature that would help drain battery life, but like many feaures on a portable, it could be turned off if the user preferred. A handheld also has the screen built in, so if it were to rumble it would have to be low enough that it didn't have the screen shaking in your hand. But even this problem would be easily solved with minimal tweaking. So it seems that the lack of inclusion has little to do with technical issues. The main reason rumble is likely not included in portables is simply because gamers don't seem to be asking for it.
But why does lack of rumble hurt a console's prospect in so many gamer's eyes, yet is okay when it's lacking on their portable of choice? If you had the option, would you want it included in your next PSP or DS?
