Worth a Buy is saying the game is very hand holdy, the AI is kinda garbage and it's made for modern audiences. He says the story is the best part of the game.
This is one of my favorite games but I think it should be free to owners of the original like what was done with the Bioshock remasters. And watching comparison videos really make this look like a cashgrab.
What Xero said. I think the game is sooo much better than FC5. I especially like the expeditions. I hope that is a staple of future Far Cry games. Best $20 you can spend on a game.
