depend the plan you have.
if you have the 15$ monthly 1game out then you may only rent 1 game at a time until you return it.
if you have the 22$ monthly 2 game out then you may rent 2 game at once and get another 2 after you return the first 2.
depend on the plan u take.
there no 1year members plan but you may be member as long as you like.
if you choose 1 game out 15$ monthly fee then 15x12=180$ per year.
if you choose 2 game out plan 22$ a month then 22x12=264$
