Favorite Arcade Shmups

This one is easy for me really - since I used to sell JAMMA PCB's for a few years and was lucky enough to play just about all of them first hand on my Jaleco Pony candy cab (some of the best video game memories I have come from this time amazingly) 
 
And the top of the list will always alternate somewhere between a CAVE, SIEBU KIAHATSU, or 8ING/RAIZING game from the mid to late 90's and early 2000's I can guarantee!
