Tell me what games you have played that you felt were amazing but their biggest downside was that they were too easy?
My top 3 are:
2.Red Dead Redemption
(somewhat big gap)
3.BioShock 1 (towards the end of the game)
But tell me one important thing - has too low difficulty level ultimately made you lose interest in the game overall? Or have you still enjoyed them greatly despite this flaw? How easy is too easy and how much could you take?
