Marcus Povey: This game looks fascinating... how accurate are the physics involved in terms of success? Do you have to hit escape velocity/learn orbital mechanics to rendezvous with the space station etc?

Oops, sorry for not replying — I didn’t see your mention for some reason! Yep, KSP is an amazing game. You do indeed have to hit escape velocity, from a planet 1/10th the size of earth but with equivalent acceleration due to gravity, and yes you have to learn orbital mechanics to rendezvous, or get to other planets. Highly recommended, but watch out — there’s a steep learning curve but once you get it it sucks you in :)

Oh, and the fan community is amazing. So many tutorials, fan videos and mods. Example:
