Alright, I got no actual idea what your games are worth but I'll assume they're all the same.
So for everything you listed (which is everything except for Burstfire really, which I'll throw in free):
Five Nights at Freddy, Songbringer, Star Story, Throne of Lies, Whispering Willows and Frozen Synapse?
to be Whispering Willows + Frozen Synapse for Command & Conquer: Red Alert 3 (Origin) + Burnout Paradise: The Ultimate Box (Origin) + Peggle Deluxe, Bejeweled 3, Bookworm Deluxe, Escape Rosecliff Island, and Feeding Frenzy 2 Deluxe (Origin) ?
