If SR IV proves anything, its that:
Super powers are very fun but get old kinda fast
No matter how many activities you add, at the end of the day for an open world game, the most important part is the world and exploration, which this game lacks a lot of and as such ruins the game and doesn't give much for a reason to continue playing or to return.
( to me anyway)
Hope the DLC are worth it,
Yup. Like I said it's like playing games with cheat codes on, fun for an hour or two but then it's back to the real game.
