Dying Light
So, this is a game I have mixed feelings toward. The story and characters are just awful and I didn't care about anything that was happening. In the first few hours, playing felt like a chore because you're so weak and the zombies are so strong that killing even a single one can take up to 10-20 hits from your shitty starter weapons. It's better to just run away than to try and fight because you're so overwhelmed. I won't mince words: the game sucked...at first.
After getting a few levels under my belt I became much better equipped to deal with the undead and the parkour system. The abilities you unlock really do make a world of difference, and once you're a few hours in you start finding better weapons that actually let you properly fight back. The game becomes much better after this, although I still wouldn't say it ever becomes great, just good. I also played it in co-op with a friend, which automatically makes a game more fun in all but the worst cases. The grappling hook, when you finally do unlock it, also does a lot to speed things up.
I paid 30 bucks for it during the steam sale and I still have the DLC to play through, so I'd say I got my money's worth. Had I bought this at launch for full price with no DLC I might feel a little ripped off. Not very, but a little. When you have a friend to play with it's a solid 7. Without one, it might be closer to a 6.
