Did you know the original RollerCoaster Tycoon 2 game from many decades ago?
Now there’s project called OpenRCT2 which can be found at http://openrct2.org/ It allow’s you to play this game under linux (or even windows or macOS)
You still need the original game-data but that’s no problem as you can still buy this game on well known online-markets (at a very cheap price)
This is one of my favourites as i’m a great fan of this genre (Starting with ThemePark) and the developer’s are still working on this great game (Maybe for bugfixes or features as this game is currently playable) Last updates were 3 hours ago as i’ve written that blog-entry.
Have a look at this great game!
