According to TMZ, Frontier Developments has filed a lawsuit against Atari for unpaid royalties related to RollerCoaster Tycoon 3. The developer of Planet Coaster and Elite Dangerous claims it's owed $2.2 million in royalties.
Frontier says that an undisclosed website, likely SteamSpy, showed that RollerCoaster Tycoon 3's sales were higher than expected. Frontier says that it should have been paid $3.37 million in royalties, but was only paid $1.17 million.
"We can confirm Frontier is currently pursuing a complaint against Atari. We have attempted to resolve this issue without legal action since April 2016. We have so far been denied our contractual right to audit by Atari, and we are unfortunately left with no other way to resolve our concerns. We are unable to offer any further comment while the matter is subject to due legal process," Frontier chief operating officer David Walsh told Eurogamer in a statement.
The lawsuit follows the 2016 releases of Frontier's Planet Coaster and Atari's RollerCoaster Tycoon World. Only one title ended up on Steam's Top 100 best-selling games list, so that battle was seemingly won. Now a second battle begins.
