Wonder what Dennis' relationship with P3 is? Seems odd that he'd be working for 2 separate companies on 2 separate games simultaneously.
If I had to guess, based on various things I've read/seen, P3 has no money, so he might not be salaried there. Heighway seems better financed. Could be that he was giving his time to P3 to help them, and maybe has some sort of back-end deal.
