Also giving an 8/10 for Dying Light so far. Feels like a much better version of Dead Island.
The added difficulty of the AI is welcome. The day/night cycle is the real experience the game offers.
The story is pretty generic. Rushing it seems pointless. I find more enjoyment in many of the side quests.
The random encounters and air drops add a nice change of pace, but can get annoying at times due to a couple mechanics.
I still have a ways to go, but these are my initial impressions with about 20 hours on it.
