Alright, so I've returned. As soon as I stepped into the garage I saw a ton of boxes and packing material marked "ebay", so I had a bad feeling. She bought and sold on ebay for years, and this was a lot of the stuff she didnt sell. Figures eh?
She sat me down and had me look over everything, but it was pretty obvious as I started that she had CRAP for games really. Tons of kids games, disney, etc. Out of probably 50 playstation 1/2 games, she had 3 decent ones - some Spyro games. Xbox/360 games were the same deal, as were the stack of NES games.
The 4 gamecube games she had were all decent picks oddly enough - Smash bros, RE-make, LoZ: Twilight Princess, and LoZ CE Collection.
I asked what she wanted for just the gamecube stuff and she said $75, no lower. After mulling around for 20 minutes or so looking at her other stuff in the garage, I came back and asked if she would split a portion of the games up, which she agreed to.
I ended up with the LoZ: CE, the 3 Spyro games for PS1, Castlevania 3 for NES, and Bart vs the Space Mutants for NES. She let me have them for $10! Not bad at all really, although quite a disappointment considering it was a 20 minute car trip just to get there.
