When I do eventually get RCT World running I'm thinking of uploading the stuff I make on both the steam workshop and here. Because I'm pretty sure stuff on the steam workshop isn't free.

The Steam Workshop is free.

It is? Goodness I've got a lot to learn about steam. I've been looking for hidden fees though because I'm sure there's hidden fees somewhere

No, there's no subscriptions, no hidden fees, no anything. The only time you pay is if you buy something.

Ok. That's good to know because I definitely don't want to get billed monthly for having steam when all I'm doing is using it to activate and update RCT World.

I was a little slow in getting into Steam back a few years ago but it's a really easy format to learn. There are plenty of perks and if you haven't been privy to the Steam sales, you're in for a treat! 99 cent sales, gifts, etc. Other Steam users can send you gifts, which is really handy at Christmas time for me. My best friend bought me PC this past Holiday, nice surprise!
