Luckily for us a generation isn't defined by sales.

I agree, this generation has been about how we interact with devices in new ways, and how they benefited gaming. 

lol. Implying every other generation has been completely original.

I would call it the mainstream gen, or something along those lines, like the kevin butler generation.

If anything this generation has been much about Online Gaming as anything else.

Just look at the shift from local multiplayer to online multiplayer and co-op. Multiplayer has been squeezed into just about everything.

Take sales out of it then, it's still the Wii generation.

*Insert patronising smiley face here - *

The Wii is going to be what you remember most of about this gen is all is said and done?

I will remember that it brought the motion gaming into the mainstream but at the end of the day it was the HD consoles that expanded upon it, not to mention drove forward the online gaming space while the Wii was still stuck in the past.

HD consoles added achievement/trophy system, more DLC, more original games to XBLA/PSN than Wii ever had for WiiWare. 

I think that at the end of the gen it will be the HD consoles that provided more for the future of the medium than the Wii had.

Of course many may disagree, but I just don't see how the Wii offered anything moving foward other than the motion control. At the end of the day it is all about the games and the experience, in which case I think the HD consoles provide more of. Just look at how they are the ones moving up.

Too-many-games-for-me-to-afford-or-play...generation.

I love you lists things under HD, but majority of that was started by the 360 later copied by Sony in some capacity. I am finding it funny that ps3 is put in with the 360, when it comes to accomplishments. 

If anything using your logic, 360 defined this generation, not HD. 

The not quite HD or half HD generation.

Online generation could fit although the most popular console doesn't have much to offer for online.

The let's try everything and see what sticks generation, HD, 3D, motion controllers, camera controllers, guitar controllers, remakes of old games from HD upgrades to full remakes, dlc, downloadable games including full games, arcade, indie, prev gen, minis, episodic games. Miis, avatars, home, achievements, trophies, cross format online functionality, user created content.

It's definitely an exciting time with all the interface and content delivery experiments.

Also that we're overblowing Achievements' long term significance vastly. That's been incidental to how games have been played or developed. Online i'll grant as a field where Nintendo has done nothing, and DLC is a mixed back as far as increasing content versus being an excuse to hold back stuff that in the old days would have been in the original game.
