The Japanese-exclusive Mad Wars 2 May have the most characters on this list. The game offers some amazing Sprite work, very detailed and colorful, and the bosses are well drawn.

Similar to Forgotten World, Battle Mania 2 allows players to fire in eight directions, and allows players to purchase power-ups between levels to improve their characters. The level design is based on your character's ability to shoot in all eight directions and will test your skills by sending enemies from all angles.
