Mass Effect or Assassin's Creed? Help me pick....

Ok, I know these kinds of topics are redundant, and this will probably be locked. Anyway, I have $60 currently, and was wondering what I should get between these two games. What has the best bang for the buck? Thanks!

More bang? Mass effect has an amazing story and a minimum of like 25hrs of gameplay, which is really captivating and has a suprisingly satisfying combat system.

Assassins creed is great also but after about 2 hours nothing new really enters the game you already have all your combos and assassination styles, and it starts to get really repetative.

Mass Effect has great replay value since your decissions can lead to alternate endings and what not.

Assassins creed was great but Mass Effect was one of my top 3 of all time.

mass effect is 10 times the game assassin's creed is (imo)

mostly depends on what your like
