wait, what do you mean epic doesn’t provide updates? this unreal 5 is a new tool and had already three updates.
the kingdom come deliverance is a fine example of why cryengine is not a good engine. the issues of that game, limitations on number of characters in the game was a result of the engine not being able to support many units. the game looked fantastic, was really nice to play, but it has this problem of not being able to support many actors in the level.
Same with star citizen, it will never get out of alpha because they are not technically able to have many characters in the level. ships or humans. They promised a MMO and at max they can have old type of multipler with limited numbers.
But if crytek is trying to fix these issues for the next cryengine that will be nice.
