So, where do I even begin? I'm a space nerd myself and play games like Mission ISS and Reentry - A Space Flight Simulator. The ISS itself is alright, but here's the thing! No audio, not all modules are accessible, the controls take some getting used to, and I've never experienced zero G myself, but I can imagine that ventilation on the ISS wouldn't push a person away, otherwise it would have a storm or something. The ISS doesn't orbit the Earth, again, thanks for that. I would much prefer if an indie developer or team ever takes this to heart and builds a full-scale ISS first, then gradually adds the physics, and releases the whole thing as Early Access. That way, step by step, you don't get overwhelmed, but do it properly. Sincerely, NewTrick2D

ISS Simulator is a space simulation experience built almost entirely around realism, immersion, and scientific authenticity. Rather than presenting space exploration as a cinematic action adventure filled with explosions and dramatic storytelling, the game focuses on recreating everyday life aboard the International Space Station with remarkable attention to detail. Developed with guidance connected to real aerospace research, the simulator prioritizes physical accuracy and environmental authenticity, creating an experience that feels more like stepping into a functioning orbital laboratory than playing a traditional game. For players fascinated by space travel and astronaut life, the result is surprisingly immersive and educational. The strongest aspect of ISS Simulator is its commitment to accurately recreating the International Space Station itself. The interior of the station is packed with scientific equipment, control panels, cables, storage compartments, and cramped modular environments modeled after the real ISS. Every section feels carefully designed to reflect the practical and technical nature of life in orbit. The station does not resemble a clean science-fiction fanta…

The game is cool, but the game just struggles to render and I get really low fps alongside graphics that are trying to go ridiculously high even on the lowest settings. the game struggles even though I've got a decently beefy PC and I've tried playing on both Ubuntu and Windows 11. Side note, there's also a couple typos in the game

Initially, I played for about three minutes and the controls are so bad I just closed the game and went to write a negative review even though the "game" is free (they're that bad). You can't write a review unless you've played the game for 5 minutes or more, so I opened it once more. I figured out how to get into first person mode which helped a ton (what even are these ball things?) In that time though, I did really enjoy the ISS and the model is so good that it does deliver in that regard exceedingly well, so it IS worth checking out. That beings said, if this cost even a $1 in its current state my review goes to negative. Pros: -Amazing graphics -Hyper realistic models and textures -Incredibly close to an exact replica of the inside of the ISS (from what I can tell by pictures and video anyway). -The Earth does turn. I was ready to be disappointed with a static Earth image and was pleasantly surprised to see that there IS movement. -You can spacewalk in an astronaut suit. Cons: -The whole control system needs scrapped. Don't even think about using mouse and keyboard. -There's constant movement of the camera object you represent. It's like it's constantly pulled down whic…

ISS Simulator is one of those simulator games that I found interesting simply because of how seriously it approaches its subject. Instead of turning space travel into an arcade experience, it tries to recreate the International Space Station and make me deal with things like zero gravity, inertia and realistic movement. I really liked the feeling of drifting through the station and slowly getting used to how different everything feels compared with a normal game. The movement is probably the most interesting part for me. In zero gravity, I cannot simply walk from room to room like I would in an ordinary simulator. I have to think about pushing myself off surfaces, controlling my momentum and positioning myself correctly. It took me a little while to get comfortable, but once I understood the movement, floating through the station became surprisingly satisfying. The interactive equipment also gives the experience more purpose. I can operate different pieces of space equipment and take part in missions instead of simply wandering around looking at the station. I enjoyed the sense that I was actually learning how the environment works, especially because small movements and mistakes…

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
