A failure to convert its free players into premium subscribers will force Lego Universe offline next year.

Representatives from The Lego Group confirmed the news Friday, saying that the MMO would be closed as of January 31, 2012, after just 15 months in operation.

"In spite of very positive player feedback and a large number of players in the free play zone, it has not been possible to convert a satisfactory number of players to paying subscribers," a statement reads.

The move will force the closure of both developer Play Well Studios in Louisville, Colorado and a marketing division in Denmark, affecting 115 employees.

According to The Lego Group, the company will still pursue further video game opportunities, such as continuing its partnership with TT Games and Warner Bros. for its line of character-licensed Lego titles.

The Lego Group took over development of the troubled title in February, after purchasing original developer NetDevil and terminating some of its staff.

In recent months the company introduced a free-to-play option and a leveling system in an attempt to stir interest in the game.
