The risks are not something we can know. They are not we put you on death row bad. The courts decide what to do. Every country has their own laws and you could be taken to court in more than one. You can get a better answer from a real lawyer not me, but that will costs money.

The worse case is if they have a registered copyright which means they get to charge triple damages. I'm not completely clear on what triple damages mean. I think that means they subtract your costs to publish the game and count only the profits, but I'm not sure. I'm also not sure if they assume your costs, or what they would have charged if they had done this (that is if you sell the game for $50 but they would charge $100) - you can bet their lawyers will argue for whatever gets them the most, and may also ask for lawyer fees.

For a small company the above will bankrupt you.
