Hi folks. I'm in Austin and haven't seen GameFellas listed. There is a popular game store (Game Over) who seem to get a lot of attention, but GameFellas have been around much longer. They also buy/sell DVDs and BDs so their stores are often merged with MovieFellas. There are 3 or 4 around the Austin area and do carry Turbo stuff, but not much. They've got all the other old consoles too, but seem to make most of their money on used 360/PS3/Wii stuff.
GameFellashttp://www.gamefellasentertainment.com/ Their website doesn't have much. I recently went to the one up by Lakeline Mall and found World Sports Competition for $30. After trading in a few extras I had lying around, I ended up paying about $22 for it. Not too bad! I've been keeping my eye on eBay for that one and it just isn't around really, not for less than $120. (The gameplay is definitely NOT worth $120). They also have lots of KCs as well as sports titles that I'm sure they'll sell for cheap for anyone needing cases.
