Learning stuff?

[the dark side]

i know that this is not related to amnesia modding aldigheri, its just a question on game programming..

are some graphics and physics engines limited to certain level design and gameplay schools? or does they just handle rendering and environment physics?

ie, if you took say, an incredibly powerfull modern engine, such as say, "Cryengine 3", (albiet modified with tri linear anti aliasing, the default code has no AA what so ever as it was designed to be console compatible.,. blugh) and PHYS-X. that has so far only been used with Linear corridor level design and Modern gameplay mechanics (regen health, 2 gun limit, A-D-S, Expanding Crosshairs, constant control hints, low running speed and a limited duration sprint function ETC) would the graphics and physics engines

1. be able to handle old fashioned Multiple route, quite open plan, Long levels with full PHyS X features (including geo mod and environment destruction) at 60 FPS without grinding to a halt every few minuites to load "moar level"?

and 2. can it be converted to render a FULL H.U.D for distinctive old school gameplay mechanics (medikit based non regenerative health and armour pick ups wioth associated percentage readouts, Static Hairs, Zoom camara precision aim, an unlimited Weapons wheel, no Hints, and a very high running speed with no sprint function) or is the lack of H.U.D built into the engines coding meaning the engine cannot be converted to old fashioned gameplay plus modern shooting mechanics (totally impossible to fire from the shoulder and hit anything+ expanding crosshairs) being forced by modern Physics engines like PHYS-X? meaning i would need to use an older engine like idtech 4, source, Team Arena (id tech III), or UR3 and an older physics engine such as "HAVOK" to have an engine compatible with old school level and gameplay design?

sorry to be a pain, aldigheri, but you do know programming, and as i said, i do have an IP of my own, the IP lease Stipulates very old fashioned gameplay mechanics, and i want to know if a Modern Engine can be programmed to run them, or if any company that has the guts to accept the IP is going to have to put up with an elderly graphics and physics engine because modern engines are "fixed" to modern gameplay and cannot be reprogrammed to classic gameplay. so, can they be reprogrammed or not?
