Hello all! After a long absence I've finally found my way back to Infinity. Played a little after Operation Ice Storm with PanO, but, really wanted to play CA. I've just picked myself up the CA Starter Pack - 3 Unidrions, 1 Maakrep, 1 Fraacta and an Umbra Legate. To start will be just playing with that, till I get back into the swing of things. I was wondering what are some safe purchases going ahead to expand on the box. Also...which set of rules is the most up to date. The N3 or the N3 Human Sphere. Thanks in advance for any replies and help!
