On Tuesday, the Scottish studio was forced into administration after lacklustre sales of its EA-published online action game, APB: All Points Bulletin.
Begbies Traynor, joint administrator of Realtime Worlds, said that the developer collapsed with debts of around £3 million.
Paul Dounis, administration consultant at business rescue specialist Begbies Traynor, confirmed that there has already been plenty of interest in the defunct developer.
Dounis said that 53 jobs from the Dundee-based studio's 210-strong workforce have been retained while a new owner is found.
"We are actively pursuing all these expressions of interest which have come from both the UK and US," said Dounis.
"We very much regret the redundancies that we have had to make."
Dounis also confirmed that Realtime will continue to trade and APB will remain available with its servers running as normal.
"The game will continue and that is something we want all customers to be aware of," Dounis said.
Speaking about the collapse of Realtime Worlds, video games trade body TIGA said that it was a "very sad day" for the UK games industry.
"Realtime Worlds is a fantastic company with an exceptionally talented team, management and board of directors," said TIGA chief executive Richard Wilson.
"On behalf of the video games industry, TIGA would like to express its condolences to everyone at Realtime Worlds. We wish you the best of luck for the future."
He added: "Despite [the] terrible news, Dundee and Scotland remain good places to do games business.
"Scotland has some excellent universities and offers large numbers of extremely talented programmers, artists, producers, managers, designers, audio engineers and testers. TIGA, the trade association representing the UK games industry, will do everything in its power to champion and support the sector."
