The fact that FO1, 2, and Tactics were top down, was a sign of the times. Even the new turn based XCom appears to have a rotating camera, and not limited to top down view, at least from what I have seen.
I would love a tactics 2 wth that kind of tech. I have no problem with VATS as my pseudo turn based combat, although improvements are nice. It is genre, story that matter most to me. Game engines, pov, matter not.
Btw just tested my theory and I was correct. Val turned into a pile of dust. Cassidy and Sullik go on murderous rampage, killing even unarmed civilians. Vic rejoins my party. Vault City hates me, no one else cares.
If I write a book, then I decide, well, I will continue this story, but as a comic. Then for part 3, I make an audio cd. Then part 4, a TV mini series, and part 5 a movie. You going to tell me it isn't my world, characters, and story, because it is no longer a book?
Btw, a scroller, is a genre. RPG is a genre. Sports games are genre. The pov does not decide the genre, IMO.
