regarding GASLIGHT,
I do own these rules, they are very interesting and I will give them a try very soon, we can keep in touch to compare the two sets.
First thing I can say is that it was SO DIFFICULT to obtain a set of VFS rules here in Europe. There is a single vendor in USA, they are not available in pdf format.
I believe GASLIGHT is so popular partly because their selling policy is different.
Tomorrow we will play a new game, I will try to give you hints of the game mechanics.
PS: if you have any link or news on the Martian rioters I would be pleased to look after them. Have your best VSF game ever very soon, don't just collect!!!
