A good game and worth buying, but definitely not a masterpiece as some people consider it. Its main advantage is the bosses and the large world (although this is debatable).
My rating would normally be 1 star if it weren't for the guides and walkthroughs available on the internet. This is because the game, although I quite enjoy it, would become incredibly frustrating without them, resulting in me giving up on it. The reason is not the difficulty of the enemies, but how difficult they have made exploring the world with no useful information and several irrelevant locations, causing you to wander for hours without knowing where to go or what to do, especially in specific quests, the use of certain keys, and unlocking areas. The same applies to items, equipment, and abilities, for many of which you have absolutely no useful information except for something very general, without telling you to what extent they help you and where exactly.
So, this is the main drawback of the game, that I have spent a total of about 80 hours playing it with around 6 hours of searching on the internet to see where exactly I should go because I was going in circles, to understand exactly what this ability and item do, to realize that I was stuck because I hadn't hit a wall or a shrine in a certain way, or that I had to remove all the pieces of my armor to make the option to open a gate appear, or that a certain key opened a door that I had passed in a different area.
But there are also other negatives. There is a wide variety of weapons, but it doesn't put you in the position to use them as some are superior to others and you acquire them relatively quickly. Overall, I have mainly used 4 different weapons so far, and if it weren't for the switch in the ashes of war, it would be a bit monotonous. Some enemies and bosses are repetitive. The battles on horseback are not good as there are times when you hit anywhere.
Changing your equipment, especially during battle, every time you want to cast a spell is annoying and takes you out of the rhythm, resulting in many times not bothering with it. While the negative effects you may have are visible on your character, their duration and degree, this is not true for enemies.
So, Elden Ring could indeed be a masterpiece but... it's not. Is it worth buying? Yes, because you won't easily find epic bosses, difficulty, and battles like the ones you'll have in this game. If you enjoy exploration, at first you will spend several enjoyable hours discovering areas and enemies, later still relatively enjoyable but using guides on the internet, and later on, you will simply start bypassing them and going straight to the bosses.
