Planet Coaster may have been officially released back in November, but the developers sure don't seem to taking that as a sign to stop putting out rather sizable updates. Back in December it was the Winter Update which brought with it a new location alongside customized rides, as well as a ridiculous amount of festive props, and this time around it is the much more grounded, yet still equally as interesting Spring Update.
The Spring Update brings with it a bunch of new rides to mess around with (including go-carts!), criminals and vandals, security guards and CCTV cameras, a variety of quality of life improvements, numerous bug fixes, and the list goes on for quite a while. If you're interested in all of the details you can find the full patch notes over at the official website, but before you do I would recommend grabbing a cup of coffee as you're going to be stuck in there for a while.
On the other hand, if you don't own Planet Coaster but feel like now would be a good time to get into it, you're in luck as its currently on a 25% discount on Steam! I personally find Planet Coaster to be a great deal of fun, but it is important to mention that its not exactly a management game - its more about creating the most ridiculously awesome ride the world has ever seen! If this is a compromise you're willing to accept, then chances are you'll enjoy it as well. Have fun!
