I understand the frustration of not having a game that focusses on being realistic. I also think this looks like a lot of fun…
With regards to the realism of the modern theme park games, there is really only RCT and NoLimits to choose from, and neither of them (well, NoLimits gets close…) get to the point of realism that is wanted in the enthusiast community. RCT has the part where you run the park, but the rides lack in realism whereas NoLimits has incredibly realistic rides…
I think this is what makes it frustrating to have nothing that combines both of these things in a game, I know ThemeParkStudio came close, but it isn't anything like people thought it would be like meaning that it failed in the eyes of a lot of people to do what was wanted from it. Apart from this promising progress that ThemeParkStudio originally made, there has really been nothing else that caters for the people who seek realism in theme park games and enjoy managing a park in a realistic manor.
In the end, RCT and NoLimits do the jobs of realism perfectly, and I am sure that when a realism-focussed theme park game is released, it will be worth the wait
This game I like the look of, it doesn't seem too serious…and it's basically a game dedicated to doing what everyone has done at some point in RCT…smashed people up using a coaster
