good games that are fun

Assassin's Creed, or Splinter Cell:Double Agent, Mobile????

i want a good game for my cell phone and i was wondering which a better game that is fun and challenging and you may want to play over and over again AC or SC:DA

Assassin's Creed is way more fun, I tried both

Skyrim: The Good the Bad and the Dovahkiin [Part 1]
