Metroid Prime and ...... Powerslave?
After playing through a bit of Metroid Prime, I started to wonder if any Lobotomy team members were part of Retro Studios. Powerslave (aka Exhumed but you knew that) was one of the few FPS I liked; Metroid seemed to have many of the same qualities to me. However, I wasn't able to find any connection between Lobotomy and RS.
Still, if you take away the Egyptian / "Stargate" motif of Powerslave, what you have is a FPPerspective game with shooting, increasing health bars, platforming, bombing through walls to find secrets or passageways, and the occasional boss. Similiar in many ways to Metroid Prime! I'm over-simplifying, but I still think there is a slightly similar "feel" to the two games.
I never played much of Turok and I never played Half-life, which some of Retro Studios' team members created. So I don't know if there are also similarities to those games & Metroid Prime or not. I just seem to notice a similiarity between the excellent Powerslave and the seemingly more-excellent Metroid Prime.
Any "for" or "against" thoughts on my theory?
