Is it me, or is that knight wielding a lightsaber?!
There are a ton of other games with slashed prices, so you'll have to check it out on your own. Be ready to spend money...
Be aware, the sale goes from 23 November through 27 November, but the deals change every day, so the prices I listed above may not be there tomorrow.
I mention Portal 2 and Dungeon Defenders specifically because they're fun games to play during FNG when there are smaller numbers present. My kids and I have enjoyed both (thanks in big part to DirtyD on Dungeon Defenders... many thanks my friend.)
