DE Star Wars is the most monotonous, least interactive, boring pin of the DMD era. A great license wasted as well.
Space Invaders is probably the slowest, dullest game that comes to mind from the SS era. Shame too, cause I love the way it looks all the way around.
Joker Poker and Fireball are the only EMs that have held my attention, can't really say on that era because it isn't my thing.
