AFAIK, the second video linked above (the youtube one) is not representative of the game anymore. They have changed the combat to be a 3rd person turn-based affair, instead of EoB/Grimrock-like 1st person real-time thing. Exploration is still done 1st person, but when combat occurs the game pauses and changes to an overview camera angle above the PCs.
This looks mighty good, but a bit shallow. I was hoping something akin to System Shock 1 or 2 with a 3-man party (that would be grand!), but I'm not getting that vibe form this. There's precious little in way of RPG here, even if they do tout is as a space CRPG. It looks to be a pretty straightforward action RPG with few gimmicks, sorry to say. Besides, like Pongo, I'm not convinced they will ever get that much money from KS.
