I adore this series, I've gotten 100% in every game, some games multiple times. Odyssey though, I played to about level 20 and just couldn't take it anymore, regurgitating the same bullshit over and over, talk to this person, go to the other side of the island (which looks like every other copy past island you visited, I expected Athens to at least feel unique, but nope) kill these dudes, go back to turn in your mission, new one pops up, recycle and repeat. What an absolute tedious affair that game is. Boring copy paste world, boring missions, characters, music, everything about the game is boring as shit except for maybe the naval shit which is okay but pales in comparison to Black Flag which nails everything naval related imo.
When I played the first AC back when it release I couldn't get very far, shelved it for a year until AC2 release was approaching, which looked great, so I thought I'd give it a try again and fell in love with it. So I'm going to pick it up again some day from the bargain bin and maybe something will click, I don't see it happening, but I'm hoping it will. It's happened to me several times over the years with other games, so who knows.
