This is terrible for the once great franchise, sure a RCT game could work well on mobile/tablets but not a dumbed down free to play (With in app purchases??) version.
I played the original RCT and RCT2 and probably lost many an hour to the game just on park planning before i even built rides then i would loose many more hours just making my park as realistic as possible with ride placement and general landscaping. Now whilst 2 was the best i did find 3 to be really fun mainly because it was fully 3D and like the other games allowed you to build a realistic park with a decent amount of tools plus riding the rides was quite fun for a bit.
I guess we won't get a decent follow up to RCT 3 but if Theme Park Studio is any good then that might be my go to game for building a theme park.
