Engine Suggestions

[triped]

I have in mind to make a very complex rpg game that requires a lot of dynamics. Although I am a programmer, I have not delved into this sort of programming so I don't know what is available. Please suggest some engines based on the dynamics:
- character fog of war line of sight in certain situations
- variable npc line of sight
- item attributes (no static item list - items are object data structures)
- FF7 styled agility determining rate of turns relative to enemies - player can have multiple turns before enemy if character is fast enough
- variable speed tile movement
- huge amount of state data - all static NPCs have stats that can change in patterned ways
- branching multiphase, multi factor combat rape (clothing, holds, binds, enemy number, current position, ...)

Please suggest some engines based on the dynamics:

Unity or Unreal.

It can also be done with Ren'py or GameMaker, but you would have to tweak them a lot for that, which would imply as much codding than with them.
