Just had a really awesome find at Goodwill. Tetris for GB, still sealed and really excellent condition, just a few bucks.
I was wondering how much something like this might be worth? I didn't seem to see many on ebay, and I noticed that this isn't the player's choice version either. I thought the original was a pack in title too, so I don't know if this is particularly rare or valuable these days.
