There is such a big market for RCT4 at the moment, I love the online idea, especially the evaluation, I can imagine you could queue up for rides, then rate and review the rides and attractions, and each individual character could have bars like: Hunger, Toilet, Thirst and fun etc, then when you want more of something (eg hunger) you could find somewhere to eat, but if you can't find a place on your park map, then you can write a thought saying "I can't fund anywhere to eat, I'm hungry" or something, I would also like to see more effort put into buildings and sideshows (games) as all you can get on RCT3 are little stalls that sell stuff.
Each player could start of with some money form there own park too... and buy stuff from other parks with the money, but comment on price too
I'm brainstorming so much that could be in RCT4
Yeah I want RCT4 I hope it comes out.
