I just didn't enjoy either Odyssey or Origins that much. The worlds they've built are amazing, , especially Origins. Something about Egypt and pyramids that greek huts or temples can't match. But the gameplay just becomes complete drudgery after 4-5 hours. At this point you'll have seen every quest variety the games have to offer but you're not even 10% through yet. If I see another fort-of-kill-two-captains-loot-two-chests-burn-2-supplies-find-the-nations-chest in this life time, I may just implode.
Storywise, I hardly remember a thing. There's just too much game spread far too thin. Odyssey is actually worse than Origins in this regard. I'd guess twice or more the size? With the same cut & pasted content essentially. Can't barely remember a single NPC or story beat in Odyssey. A couple in Origins.
Forts.
Forts.
Bandit camp.
Leader house.
Forts.
(For the uninitiated: they're all different size forts)
Bounty hunters, aka that terrible nemesis imitation (to be fair, I didn't enjoy it in SoM either): Thankfully they just let you pay off the whole thing for a pittance from the map screen anywhere. It's ridiculous how every bounty hunter in Greece automatically knows where you are and you will literally finish slitting the throat of the first guy when the horns sound again, announcing the approach of the next guy. And the next. And so on. I once lost an entire fort clear worth of progress because the buggers just kept on coming and you can't really take that many hits on hard.
On that note: Incoming poison is ludicrous (on hard at least). A single hit from Sir Bulletsponge will kill you unless you have the heal/status clear skill ready.
Second note: You can't save in forts. Some of them are huge. A workaround is to exit the "hostile" area which allows you to save and not have to re-clear/assassinate every last henchman all over again if you or the controls mess up and you get spotted.
Oh yeah. It wouldn't be Assassin's Creed if the controls didn't regularly betray you. The addition of a descend button has certainly helped but whenever the game expects speed or accuracy, you may just find yourself glued to the wall you were trying to get behind while arrows slam into your back..
Odyssey also has that completely Oblivion-esque leveling system where getting a level ironically means you
lose power, once you no longer have more core combat skills to gain at least (the "end-game" stat modifier points don't amount to much). You level up, your enemies immediately scale to your level (unless you disable scaling for a truly snooze-worthy gameplay experience), but
your gear stays the same. Meaning you have to upgrade all your stuff every 5 levels or so to keep up. Again, it's just a tedious task to perform. And it actually becomes quite expensive. Unlike most RPGs where you're swimming in cash by the end, you will not max your ship and character in Odyssey short of spending 200+ hours. Not that you need it, but, you know..
Will give them credit for the DLCs though. Feels like a proper expansion and is actually more focused than the main game (though fear not, there's still forts!).
Uhm. So yeah. Dear diary, nobody's ever going to read that but I feel so much better now
