Sueing someone for making what may be a poor game is just a complete nonsense and really not worth further discussion.
You will be arguing against consiquential entertainment loss next on the grounds you could have spent your free time better doing other things
Seriously return the game the retailer is your only sensible recourse, after that it is the retailers problem to sort out returns/damages/defective good etc.
To my mind UBI greatest sin in all this is the lack of information and communication, but there is no law against poor customer support I'm afraid (unless your like a government buying defence equipment in which case they change the law).
