I can't get this game out of my mind, but I can't remember it's name. Back between 03-05 I started playing my first real online game. It had the graphics of maplestory, I found maple story through this game, I think both were made by Nexon. Anyways, it had a queue style like League does.
You queue up, get paired with other people and select a tank type vehicle that your character sits in. The games maps were 2d and looked like Maplestory, the point of the game was to charge your attacks and fire them across the map, usually lobbing them into the air and either hit the enemy tanks, or destroy the ground under them to drop them off the map.
