Congrats for your initiative, it brought back to my mind dicesites.com the service that NLNico ( it's pity he is not active here anymore) launched back in good old days ( https://bitcointalk.org/index.php?topic=877078.0).
First thing that catches my eye is that the progenitor of all crash games is missing here Bustabit.

Also accept my little suggestion, to try at least monetize a bit your efforts , to add a ref link for all the sites you keep track of and not only one of them : I think you deserve a little compensation for offering such a service.
