We had an amazing day on May 15, as we organized SCS Fay Day Experience #4! We welcomed fans of our games from all around the world to our office in Prague, where they had the opportunity to meet our team, tour the studio, and get a behind-the-scenes look at how our games are made.
After receiving a huge number of applications for this fourth edition of our SCS Fan Day, we had to narrow the list down to a smaller group of some of our most dedicated fans, including visitors who traveled all the way to Prague from countries such as Brazil.
As always, it turned into an unforgettable experience meeting and chatting with members of our #BestCommunityEver. Once everyone arrived, they took on the challenge of driving on our 4D motion simulator before heading out on a tour of the office. Along the way, we stopped by several departments where our colleagues gave them a behind-the-scenes look at what they are currently working on and how the development process looks at SCS Software.
Later in the afternoon, we hosted a special Q&A session with our developers and CEO Pavel Ε ebor, where we discussed the community's thoughts on our games and answered plenty of questions from our guests. The session was accompanied by delicious snacks and coffee before we gathered for a group photo, handed out bags filled with SCS merchandise, and unfortunately had to say goodbye - at least until we hopefully meet again someday!
We would like to thank everyone who took part in this year's Fan Day. We hope it was a memorable experience for you, because it was certainly unforgettable for us as well. Your passion, support, and willingness to travel such long distances just to meet us truly means the world to everyone here at SCS Software, and it continues to motivate us every day. We also hope to meet again with everyone who applied but was not selected or was unable to attend this time around.
We hope we will be able to host another Fan Day in the future and meet even more of our amazing fans. Don't forget to give ourΒ X/Twitter,Β Instagram,Β Facebook,Β Bluesky, andΒ TikTokΒ a follow, as you'll receive news from any upcoming events straight to your feed, orΒ subscribe to our newsletterΒ to stay informed.
