Something to consider generally about 90's game production is the interplay between the in-game assets, the cutscenes and the production models that were evolving at the time. The software itself is a factor in this - and there was hardware, too, a lot of Silicon Graphics workstations were used in the mid-90's - but the device constraints at play dictated the idea of pre-rendering 3D assets for games like the Diablos and Resident Evils, which in turn made it easier to consider reusing them for FMV. That in turn produced the "parallel pipelines" mentioned in omershapira's comment whenever the engine was actually capable of 3D: often games were pitched to publishers by producing a cutscene trailer, and then the development team figured out what the engine tech could actually do as they went along. Because the in-game assets were still very basic and produced relatively cheaply given a design spec, this served a combination of development and marketing goals. Lara Croft got on all the magazine covers because of the high-poly CGI, not her in-game version. (Why would publishers focus on assets? In this period, acquisition was extremely common as the industry got bigger and financing new projects got more risky, and so publishers gravitated towards a practice of shopping around for IP development and staffing at a low price. What they were banking on was not getting just one hit or a powerful engine, but a franchise that would sell well for years and experienced developers that they could put on their own projects. Likewise, studios were hungry to get publisher support and their heads often settled for an acquisition rather than shutting down. Focusing on asset production was a way of meeting in the middle, since the tech was so often an unknown; if you acquired a team that could make good assets, then plugged them in with an in-house tech team, a product could be made.)
