I500 video mode is quick and doesn't come around that frequently. It is difficult to beat, but not impossible and offers an extra ball at the end. I'm a fan.
Blackjack in Maverick is a small but good one (in my opinion) for lighting the kickback. Gives a nice "video poker" feel to the machine for a brief moment.
I can certainly attest to the statements about people not knowing what to do when the ball locks up and I usually have to tell the player once. Same thing happens on my X-Men for villain selection.
My 2 cents.
