Now is time for a super-hard one no one will get.

The letter C appears after the letter D. Can you please confirm that you don't know alphabetic order and it's not just a typo?
Yes, I fail at the alphabet. :(
The worst part about that cheating method is that the games in question probably aren't even dictionary words. =P
All the words in the game titles are, in fact, normal words and each one is there in your list. :)
If it wasn't for the fact that you cheated and didn't come up with that list yourself, I'd probably give you the prize. ;)
Can we get a clue as to what system it is on?
If no one has it within 24 hours, I'll give a hint... but I dunno about telling what system they're on... :)
