Stationfall was interesting; in some ways, I liked it better than Planetfall, although it might just be that there was so much hype about Planetfall that I found it disappointing.
Stationfall has you flying with Floyd to a space station to pick up some forms. When you arrive, the station is deserted... mostly.
The map is interesting. There is a main sphere with 8 or 9 levels. The top and bottom levels are one room each, while the middle level has fifteen or so. In addition, there are three sub-modules attached to the middle level, two of which are joined together in a big space village.
This all reminded me a lot of Starcross with its huge cylindrical map and space village. But Stationfall's map had more flavor, I feel. Meretzky has plenty of references to Planetfall, including leaving bedistors and other computer equipment laying about, as well as similarities in recorded equipment about. There is an alien code whose solution reminds me a bit of HitchHikers' Guide to the Galaxy, which is explicitly mentioned several times in the game through footnotes.
The story starts slowly, but picks up. I really enjoyed the ending sequence, and felt it provided a little more closure than most Infocom endings.
The hunger/thirst and sleep timers seemed a little easier than in the original Planetfall, although many have mentioned the tight time constraints in the game.
