I have been playing AC Odyssey lately, and still feel I am rather close to the beginning, despite nearing the 60 hour mark. That all is a bit weird, as previous ACs even if they were good had some serious issues keeping my interest after about 20 or 30 hours or so. Last summer I was playing AC Brotherhood, and even though it was a good game, at one point I just wanted it to be over. I managed to get Black Flag past the 50 hour mark, but I had to stop and restart twice because I lost interest. Odyssey on the other hand it much closer to that real kind of RPG gameplay that I like, to the point where the repetitive missions become a bit grating.
One interesting part of the experience is that despite advertising the presence of a medusa in the cover art used for Steam... there actually is very little fantasy in there so far. Besides the typical Assassin's Creed fare of people who can hang on to tiny precipices with their fingertips while wearing heavy armor, and the ability to survive falls from any height as long as there's a small heap of leaves on the ground. But that's all explained in the more sci-fi elements of the setting. Which makes the game the most low fantasy RPG I have played so far I think. The setting is ancient Greece at the time of the wars between Sparta and Athens, which also is rather convenient because that was one of those periods we learned about in school really well.
If there's one thing that annoys me though it's the crowded world it presents. Unlike World of Warcraft for example, which is a great example of building a world that is both small but looks big, this one grates my suspension of disbelief almost immediately. It's all ok when you are on the tiny island at the start, but once you find an Athens where the walled passage to Piraeus is a 100 meter wall section, and where you can see the houses on Salamis from the port... yeah. Everything's a bit... small.
