Great replay value for the money. Devs actually listen to their community. Game is still getting content and patches applied to it well after the fact. Would definitely recommend.

This isn't a PoE killer per say but its definitely up there. I'm 69 hours in (...Nice) and I have no shortage of quests and game mechanics to unlock and try out. Even the most benign of tasks completed successfully triggers a dopamine rush like no other. You gained a level in gathering - prepare for a fireworks and color display.

Negatives About the Game:
The game takes FOREVER to load from the time you hit launch.
Some of the keybinds are completely unchangeable from their defaults
The UI doesn't remember window placement between game sessions
The number of buttons you can have per page of a hotbar and the restrictions on what can be sloted into certain parts of the hotbar are silly. This is specifically in reference to slotting songs.
Tons of RMT spammers right now due to the games newness
The chat has a limited number of slots to block players which makes me wonder if its stored server side

If you played Killing Floor 1 I think the main issues you'll come across are:
Welding doors seems to be completely non-existent as a strategy. Folks tend to gravitate towards general defensible areas on the map but the Support class role of welding is completely marginalized.

Beyond that my only other gripe is the bonuses/level for the commando are a bit lackluster.

If you've never played the original then I think most folks will enjoy a good co-op fps like KF2.
