Not really sure what I was expecting but I borrowed a laptop just for the sake of seeing what would happen!
The minimum RAM is something like 4 or 8 GB.
My chosen laptop has 1 GB.
More background info: It is an Acer Aspire One D270, using Windows 7 and the CPU reads as Intel Atom N2600 with 1.6 Ghz.
Text seems very small
The music works perfectly as do some sound effects.
Graphically things function ok until the end of character creation.
Once out in the field visibility drops severely, about 30% of the surroundings can still be seen. (my character is out of sight except when there is dust around)
This is with all the extra effects disabled in settings
User interface is tiny but usable
Overall I was kind of impressed. Getting past the title screen was already a surprise but I daresay the game was almost playable even without being able to see anything.
