50th Birthday Invitations

You've seen a several samples of Quinceanera and wedding invitations, but lately I've received several requests for birthday and graduation invites.  :)  A friend of mine's husband is celebrating his 50th birthday soon, and she asked me for help with the party invitations and theme. 

The colors are Real Red, Basic Black, So Saffron and Whisper White with a gaming theme.  Here's the invites:

The image on this card is from the stamp set called Card Games, but I'm also using Game Night on the inside and creating a matching envelope with the In the Cards wheel.
