Perhaps one of the best games when it goes on sale for 20 euros on the Nintendo eShop, making it one of the most value for money games. If you like games that involve exploration, comedy (about 60-70% of it is comedy, and it also includes Greek mythology, so if you're not familiar with it, you might not understand many jokes), puzzles and hack and slash battles, you will probably be satisfied.
I have around 70 hours of gameplay, and I would say that to complete the story it takes about 15-25 hours (the first time without any help from the internet).
Obviously, you can also choose not to continue the story and do other missions, which can take you another 30-40 hours because you wanted to become stronger by collecting new armor and upgrade materials. To achieve 100% completion without including the DLC, it might take you around 100 hours. You always feel like there is something to do and something hidden where you least expect it.
The comedy, as I mentioned, breaks the monotony and is quite good, especially because there is voice acting/conversation between Zeus and Prometheus, giving it a lively feel. In the end, I would say that I learned some mythology that I didn't know before.
The graphics, as far as the Switch is concerned, are quite good, I would say even better than Zelda Breath of the Wild.
The battles are something in between Assassin's Creed and Zelda, with additional unique touches that I have only seen in Immortals Fenyx Rising.
The game's performance is quite good, stable at 30 fps, and the graphics impressed me.
It has Cross-Save, so you can save your progress and play on another console if you have purchased it elsewhere.
It has many side quests, some of which you acquire in the game, and some from the merchant Hermes, who sells different things every day. You can buy these side quests with money you collect from missions that the game gives you when you connect to the internet, or by purchasing them with real money.
If I have to mention something negative, it would be the "Tartaros" which are separate levels within the map that usually involve the main story or finding new equipment. What I didn't like is that after a certain point, everything seemed the same, and the puzzles sometimes felt like you had already done them somewhere else, resulting in getting bored quickly in some cases.
As for the puzzles outside of Tartaros, they are always different.
In conclusion, 20-25 euros for many hours of gameplay, DLC, events, good graphics, a good combat system, and a game that makes you laugh makes the whole package amazing and worth every euro you paid. If you liked Breath of the Wild, then you will also like Fenyx Rising.
