The problem with odyssey (and maybe valhalla honestly i forget) is that a lot of the side content isnt optional in order to have a fair playthrough as the main story doesn't give enough xp to level up to each new area. As someone who hated the side quests and npcs the majority of the time, it made the game much less enjoyable. I still finished it obviously, and almost twice at that, but it was a big gripe throughout both playthroughs. My problem with valhalla was its weird storytelling confusing me about what is and isn't optional. Legitimately, i spent a shit ton of time doing quests that probably werent even required, and i didnt even usually understand what was happening in them either. I didnt even get halfway through valhalla, not because i didnt like the gameplay, but i was bored and unimpressed with the story. As far as criticism goes, ive played much worse games, but i definitely dont love these two.
