I'm enjoying Odyssey but I wish they'd lean more into actual RPG elements. Like, meaningful choices and all that. There's a definite conflict between the completionist structure of AC and the exact opposite structure of RPGs. AC:O has a faction system but it's completely superfluous. There's no reputation system so you can kill 1000 Athenians and still do Athenian quests. The only difference between Spartans controlling an area vs Athenians controlling an area is the color scheme of the banners and paint. Same goes for the bounty system which you can completely negate by simply paying off your bounty in a menu. As for the narrative choices, those also seem superficial. Early in the game you can choose to save some sick villagers and if you do, the rest of the island gets sick but nothing really changes from a gameplay standpoint. No relevant NPCs (not even merchants) are killed, no quests are closed off, nothing happens except for aesthetic changes to the towns.
If Ubisoft really wants to go full RPG, they need to suck it up and say "no, you can't do everything in one playthrough." There need to be meaningful choices with long-term repercussions that actually affect gameplay.
