I agree with Runa, the first episode looks so boirng nowadays. I don't know how many times I wanted to play with it.
But I always gave it up. And that's the same with the others. II, Brotherhood, Revelations. But Black Flag (Freedom Cry DLC too), Rogue, it's my game.
The atmosphere of it, the characters, the storyline, very detailed and good. Few days ago I started to play with III (never before), I'm at the beginning of the game, just finished the tutorial with Desmond.
Unity is not compatible with my PC, so I won't play with it. I tried it, but it's laggy as hell.
The only problem with Rogue is the short story. It has only 6 sequences, Black Flag has 12...But, Rogue has a never ending collectible stuffs. I hope Ubisoft doesn't want to offset or compensate the short story with the collectibles, it would be sad.
I hope Victory will be better optimized than Unity. And they don't release tons of patches with a huge size.
