Can we bring back previous "free" games as Bundle Games please?

Note: This isn't a begging/"wanting to win more" thread. I have all of these games already.

So, it seems whenever a game has free copies given out, it's removed from the site altogether. This remains the case forever.

While I can understand removing them to prevent a flood, it would be nice to see them come back as Bundle Games after a cooldown. I doubt people will hoard keys for months just for "Bundle" Contributor Value.

There are some quality games that have been removed that would be nice to have back in the giveaway list; such as:

• Metro 2033

• Rainslick 3

• Defense Grid

• Others?

• EDIT: NOT DOTA2 (Didn't think this needed to be said...)

Now, some of these were recent, so they can stay off if need be; but it would be nice to have them back one day. I know some people who even bought extra Rainslick copies to giveaway!

Thoughts?
