Roller Coaster Tycoon rip-off! Mega Park

This sucks. I finally, finally win every scenario in RCT original and turns out Mega Park is just the shell of Megaworld Park from Loopy Landscapes! Guest count (at entrance), themeing, even paths leading to the rides are the same! I was expecting the expanse of flat land and every ride/unlimited cash, what the hell gives? Is the flatland/freemoney 'Mega Park' a trainer-only thing or is that the reward for loopy landscapes?
