This is one of the greatest games ever made. This is a game that really tests you as a player and teaches you everything you need to know to beat it, the hard way. When I first got Bloodborne, I spent a long arduous time getting to the first boss who I struggled to get anywhere near beating. I got so frustrated with the game that I sold it off. However, over the next few weeks I had this craving that I needed to have another go and that if I just had done something different I could have beaten the boss. I rebought the game and managed to beat the boss, giving me a feeling of true achievement. This game punishes you by beating you down, over and over and over and over and over again. However, it also gives you a quick glimpse of what you did wrong and what you can improve to do better next time. I am now on my third playthrough of Bloodborne, verging on unlocking the platinum trophy, something which originally seemed like a challenge as impossible as beating that first boss.
If you like a challenge and are happy to try over and over again endlessly for a great feeling of success, Bloodborne is your game.
