I've only played a handful of Ubisoft games to my recollection, but I've never paid a penny over the purchase price of the game. I don't play games online so I've never felt the need to buy the Casablanca Go-Go Girl Warrior outfit or the sequin encrusted AK-47. I put the disc in the machine, I let it load up, I play through the single player story over a period of days, weeks and sometimes months, then when it's over it either goes into the "might play again sometime" pile or the "take it in for store credit next time I want a new game" pile.
If you've played one you played them all
Every Ubisoft game is an assassin's creed reskin with the exact same UI and an even bigger cash store than the previous title
