When earlier in the year CB announced the future release of N3 they stated that the CP and HS books would be 'compatible' with N3. I'm new to Infinity (awaiting my starter set) and wonder why I might need these other two volumes upon release of N3.
I realise this requires we make assumptions about what comes in the full N3 rules book. I'm assuming new stats for all existing factions/models (which will also be available via various online tools). I see from the N2 based Wiki that additional skills and associated rules were released in these two volumes but would expect these to be updated/consolidated in N3 rules.
So why might I need to buy the Campaign Paradiso and Human Sphere books apart from fluff and playable scenarios?
