Currently playing Hollow Knight. Didn't think it would be my thing, since I prefer games that are more linear. I got to say I am having a fantastic time with it. It is the third metroidvania I have played (The first two being Mega Man ZX and Mega Man ZX Advent), and I am surprised with how I have not gotten bored of the world since there is a good chunk of backtracking. The areas look so stunning, alive, and even psychedelic at times, that backtracking through them again still feels fresh and immersive. The boss fights are very tough, and the challenge definitely gives it more of a personality. I am currently 30 hours into the game, and I feel that I am still far away from the final boss. If anyone is looking for a game to get very immersed in, then I definitely recommend Hollow Knight. It is probably the best £11 I have ever spent.
