I love this game! I was gifted it but I bought the DLC in order to spend some more days in the Far West!
The luck fighting system can be tricky at first but it's way better than RNG once mastered. I played almost everything on hard without saving (you restart the fight when you lose) but for the DLC on hard I admit I hard to save my games after restart 4 or 5 times the 2 first fights.
