OT - Advice

I have a whole bunch of video games that I never use anymore and I want to sell them on eBay. Trouble is, with the advent of more modern video games, I don't know what fair prices for them would be. I hope that if I list the items here, you all can help me decide what prices I should put on them.

Please keep in mind that I am not spamming. I am not asking anyone here to buy these items, I am simply asking for advice on pricing them.

Systems(all of which have their attachments):
Two Sega Genesis (Two controllers each)
Sega CD (Uses same controllers as Genesis)
Playstation (original version, has one controller)

Games, Sega Genesis:
Two copies of Sonic the Hedgehog
Sonic the Hedgehog 2
Ms. Pac-Man
Street Fighter II
Sonic & Knuckles
Mighty Morphin Power Rangers the Movie
Clue

The games and systems will be grouped as thus:

(Sega Genesis, half of the Genesis games)

(Playstation One and all of its games)

(All Super Nintendo games)

(All Game Boy games)

Everything is in good condition, with the possible exception of one of the Playstation games, which appears to be scratched. Any help would be appreciated. Thank you very much.
