Stargate.
It's more of a challenge.
ditto.......also Stargate (coin-op) had a menu select screen that was so advanced for its time. You could custom set tons of stuff on the game including the starting and ramp up difficulty. The operator could even put a custom message up on the screen.
I think of it as a deluxe version of Defender, what with the vast expanded run of enemies...
Stargate for sure.
