The game was originally being built using Unity 4.6, but the RCT Team decided to take advantage of the graphical benefits afforded by upgrading to Unity's brand-new engine that launched earlier this month "We hope to take full advantage of the many new environmental, lighting, and shadow improvements as well as many other features in our original Unity 4.6-based engine to create a game that looks great," the team said in a post on its blog. "Our early results are extremely promising."The RCT team also provided an update on when gamers can expect the game to be released, noting that RollerCoaster Tycoon World won't be rushed out the door just to hit its initial early 2015 release window . As such, fans may have to wait a little while, but the team is confident it will deliver on fans' expectations."We will not release the game until we know that it is truly ready," the blog update added. "If the game needs to be 'put back into the oven,' then we will do it. We have waited for more than 10 years for the next great edition of RCT, and we plan to take the franchise to new heights with RCTW. We will take the time required to achieve that goal."The studio plans to share more specific release information later this year.
