OK, I hope everyone reads this and that it makes sense to them. I would love input on everyone else's way of thinking. I am analytical, so this runs in my head like a computer program, but for the lack of a better phrase, my logic could be flawed.

I tend to undervalue portable gaming. I never bought portable games, so I don't really have a memory of pricing from the early days. I've noticed that in the world of portable gaming, the systems are usually worth more than the games. Where in console gaming, the games are usually worth more than the system (on average).
My rule (which I know is low for the systems and too high for the games) is $5 for the system and .25-$1 per game. I can't speak for the others, but it should probably be more like $10 for the system and .25-.50 per game.
Obviously pokemon stuff would be an exception as well as anything that is CIB/a premium game.

Your lot is a prime example of how little I know about gameboy stuff. Based on amazon values, you did pretty well.
If I had seen the same lot in the wild and I was forced to make an offer for everything (I usually wait for them to make the first offer), I would be around $15. $5 for the system, $1 per DVD, $2 each for the games since they are "better" games (and not all "spongbob" or "that's so raven").
If he countered with $50, I would say were are pretty far away on pricing.
At this point they would tip their hand on what they value in the lot by saying something like "Well the systems go for $50 on ebay" or "The games are worth much more than that!"
Either option will help you know
where they are flexible on pricing and what to go for if you can not come to an agreement on the whole lot.
Let's say the response is: "The games are worth much more than that!"
I would ask: "OK, How much for just the system then?" Let's say he says "$10". I'd then say "OK, so the system is $10 and the DVDs are $1 each, so that means the games are around $9 each. That is a lot higher than I pay for any game.
Usually I see gameboy games between 25 cents-$1 each."
*warning* Whenever you make a statement like that the person always latches onto the higher value in their head. They hear "$1 per game" because it is the highest value you placed on them.
I would then explain how I came to my offer (like I typed out above) and say something like : "I don't have these games yet, so that is why I am willing to pay $2 each for them."
^^^This statement is a double edged sword. It could help or hurt you depending on how the other person takes it (and as you learn to read people, you will know if it is worth saying or not). It could either put the idea in their head that the games are GOOD/undervalued because I am willing to pay more for them OR It can add legitimacy to my offer by saying normally I pay $1, but I am making a one time exception because these are not doubles/because I want them for my collection.
At this point most people will try to squeeze a few more bucks out of you and offer $20 for everything. If you want to be a hard ass and stick to your guns, you could try $15 again, but most of the time, I will take the lot for $20 because it leaves both parties feeling like they accomplished something and that is was a decent deal. (win/win).
I'm going to assume he and I settled at $20 because I am too lazy to type out other "what if" scenarios and I am not sure anyone is actually going to read all of this. lol
