Two former shareholders have alleged in federal court that an auto-racing video game creator swindled them out of more than $200 million in stock.

In a complaint filed Monday in the District of Delaware, HC2 Holdings 2 Inc. and Continental General Insurance Co. allege majority shareholder Motorsport Games Inc. portrayed 704Games Co. as being unprofitable and bought out their shares for $1.2 million, then months later went public with shares trading at more than 170 times that buyout value.
