Computer game: Space Station Manager

Hi all

Please excuse the X-posting.

(a) I'm not sure where this is appropriate.

(b) I'm never sure WHERE my posts will get through these days.

Anyway I bumped into this on the 'Net recently:

http://www.mistaril.com/space_station_manager/

Simulates building a station.

I'd like to know if anyone else has played this?

If so, how accurate is the modelling, especially the thermodynamics of
managing the station?

Is it worth the US$ 20.00 for the full version?

Many thanks for your time and regards
Frank Scrooby
