Well that's your opinion my friend, in my opinion the Road sets a much darker, scarier future and packs a much bigger emotional punch. But yeah tis a good game
The Road and LOU have a ton of similarities. Both pack an emotional punch but imo LOU edges out The Road because I felt more attached to characters in LOU (although thats comparing apples to oranges, games to books). You're right about The Road being a bit more dark because there is absolutely no hope.
