Kerbal Space Program

...then this game should be yours. The start is relativly easy but later challanges are tough to conquer. Every successful step of your space program will be very satisfying. (First Orbit, First flyby of the muns, Landing there, First docking in space) For all of this achievments there are also tutorials in game and in youtube... You will be constantly learning things about real world aerospace and physics. Give it a try - there is an up to date demo! The full game will be content updated for the next time so it is worth every Cent. The game is practically free of bugs The downside of KerbalSpaceProgram is: after playing this game a while, movies like Gravity or Star Wars will appear physically incorrect ;) Happy launchings!

This software uses a tracking spyware called Redshell. This is most likely not what a GOG user wants to support. See (german) http://www.pcgameshardware.de/Spiele-Thema-239104/News/Drittanbietersoftware-namens-Redshell-sorgt-fuer-Diskussionen-1259059/

Great game ruined by spyware! Don't buy this game!!! Apparently buying this game is not good enough for the greed gob publishers they now want to make money off your private data. Scum. Don't buy.

Just playing the game gives T2 the right to collect tons of data, including your name, photo and address.

A very fun game, with alot of mods that really keep the game going. Its quite challenging and some of the contracts ingame career mode will literally drive you nuts. Anyway onto the more important thing, the spyware the part that i was skeptical about as well. Its integrated into the .exe now. But theres a caviet, you can opt out only during the first run of the game, heres the opt out, the token is generated based on your machine snapshot at the time of token generation. Lets you opt out of being "spied" on but then again, it already took a snapshot to phone home with all of our devices information. To me this is a big BIG turn off for any game, and or developer to implement. Hard core privacy invasion and intrusion. Just a huge heads up if you buy this game like i did, wondering to what extent the software inshort spies on. Also to determine whats being phoned home about your machine now, its all clearly stated, but you need to attach a debugger to the games ksp_x64.exe to find where it all points too. Current opt out link from the unity appliction (Token= is your devices unique UUID which ID's your hardware, your device). "https://dataoptout-ui-prd.uca.cloud.unity3d.com/?token=" "sdfajmephivkohlcvlm2234rg4h5t0lvo8l9prr8tkobses56r345prf5p4s" Now if you can get past the fact these devs literally spy on you if you don't opt out during first runtime and you don't see the notice again (unless you reinstall the game), then this will be a fun game. Especially if you only intend to run the game on a unnetworked device, then it wont really matter because the software can't phone home, if theres no network connectivity period. Or you could literally block everything network associated using windows or linuxes inbuilt firewall management associated with Kerbel Space Program.
