I do not know if anyone here has heard of this, but Coaster Madness is a community-designed video game, similar to RCT3 but it promises to be much better. Right now they are in the planning stages of the game and are looking for people who can help with ideas and design. Having read through some of the posts there, it seems promising, as it will give much more freedom than RCT3, and that will help in being able to create favorite Disney rides that are otherwise impossible on RCT3. I am not affiliated with the site in any way, as I am not that good with computer technology, but it seems like it will be good, even if it is a long ways from being completed, and I though some here might be interested.
