That's not really relevant at all as they are completely different and unrelated games that have literally nothing to do with each other. There are clearly some gameplay similarities between RCTW and Skylines (path-building mostly) but that doesn't mean anything substantial at all. City builders like Skylines, SimCity, Cities XL, etc are essentially economics sandboxes (based on broken, outdated old urbanist principles, although that's a different conversation) where the only design aspect the user has to worry about is general layout. Park builders are almost exclusively design-based, and making them shiny (RCT3, RCTW) is useless if they're not extremely moddable, easy on system requirements, and graphically unobtrusive (RCT, RCT2). There's a reason Minecraft is one of the most successful games ever.
I'm still going to buy RCTW and I'm cautiously optimistic about it (it will be better than RCT3), but RCT2 is most likely going to continue to be the cleanest park builder and the best long-term game experience on the market.
