Melancholy
This is one of those games.
I think I actually went out of my way to accumulate every quarter possible to play this whenever I got the chance.
Other than Gauntlet, i can't think of too many multiplayer arcade games from this time period. But RAMPAGE! had a one up. What you did in the game could affect the other players. I think this is revolutionary in the videogame world at the time.
I could still play it today.
In fact I may just get the whole thing on eBay or something...
