By this, I mean is it the American Release or the UK Release?

The UK release had a recreation of Blackpool Pleasure Beach, and US had Fort Achronism if I remember correctly. UK Was also called Added Attractions, and US Corkscrew Follies

Which version is it? It's not much, but I'm curious

Thanks!

From the gamecard: It's the US version, but it contains the UK-specific scenario as well, since it was included in the Loopy Landscapes expansion.

Great, thanks!

Its just, according to the wiki:

Alton Towers was included with the Loopy Landscapes expansion with Heide-Park and Blackpool Pleasure Beach and was updated to take advantage of the new game components. Both scenarios are also included as part of RollerCoaster Tycoon Deluxe. The UK edition of RollerCoaster Tycoon Deluxe contained Blackpool Pleasure Beach in place of Fort Anachronism.

That kind of makes it sound like the US version of Deluxe (Which I'm guessing this is) Doesn't have BPB.

Can anyone 100% confirm that it's in?

It is. From GOG's RCT1.

It is the US version. UK had Added Attractions instead of Corkscrew Follies, and BPB is in there!

All versions of Loopy Landscapes include Blackpool Pleasure beach.

The file is called BPB1.SC4 and is included with the GOG verison.

The GOG version is the US version of RCT deluxe. Other languages can be installed with a hack.
