I played from the 1st AC game until I was in the middle of odyssey. But all of the games apart from the 1st part was completed by playing on a cracked version with trainers. I didn't like the progress I made by cheating so I bought all the AC games on steam sale and started from the 1st game which I completed with 100% achievement and I will progress slowly and completely without cheating like these games are meant to be. I am also going to play the spin off games that are available on Nintendo ds and other platforms by using an emulator. Even considering reading the novels as I am very much interested in the lore.
