Personally I think it mistly sucks.Most games are bad and are designed to be addicting in small play sessions, but are as deep as a pool of water and have zero story and so on.And while there are some hidden gems that are excellent, I like 1000 times more playing on a handheld or home console than phone because of controls, atmosphere, etc
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
