You could probably get more as individual buy it nows, but either way you're going to get some nice pocket money for that lot.
If you need help with values, look for current listings or recent ended ones on eBay and see what each went for. Add the values up and then take 10 to 15 dollars off and you have a buy it now price tag for the lot of them. If you don't drop the value and just eat the shipping costs and list it as "free shipping" it will sell a lot faster.
Either way free shipping or no, drop the total estimated value by 10 to 20 bucks and it will sell.
Or if you want to do individual auctions, or as a set, you can test the waters and if you don't like how it's going by the 4th or 5th day etc end it. You shouldn't get penalized for ending it but check to see what the deadline is for calling it off before you start it up, if you do decide to try an auction.
If you want to see about shipping costs, inside the US, look at current listings for each and there should be weight listed somewhere I believe (I may be wrong) or you can check the packaging for each game as they usually list weight or at least they do on food. All else fails check the Wiki for each, I don't know if they list weight or not and when you have a total in LBs call your local post office and ask them for shipping rates for that weight.
I hope some of this helps, and good luck.
Oh yeah, you probably wouldn't get as much with this being CAG, but if you wanted to trade them you could start a thread in the trading section of the forums and see what offers you get.
Again good luck and I wish you the best my fellow CAG.
