This time of year ( usually go through my collection and sell around ten to 20 titles that I feel my collection could do without (and spruce it up a bit). I sold around 20 games today, mostly early 360 sports games, and "crud" bargain bin common titles, and gain nearly 100 bucks - way more then I thought I'd get from GS.
I picked up 3 Wii games with the cash,
Mercury Meltdown Revolution, Wii $16
Big Brain Academy: Wii Degree, Wii $40
Mario Party 8, Wii $40
They are all used, but they are all like new.
Yesterday, I bought Geomerty Wars: Galaxies, Wii New $30
Battalion Wars II, Wii, Used, $27 like new shape.
My collection feels better =P
