Eternal Ring

Eternal Ring was an interesting FPS for the PS2 because of a few factors:
 * the player could look up or down and this was important for aiming at short foes like grabs or flying foes
 * this worked very slowly so it took a lot of prep time, not quick and easy like using a mouse in computer FPS
 * there was a focus on melee combat: there was never any free-use ranged weapon, only eventual access to spells (starting with fireball) which cost mana which was hard to come by early on since you had to kill enemies or use potions which you'd probably want to save for healing
