What about the idea of a Multiplayer “Large-Battle only” Act IV?
I know this would be far into the future, but nevertheless a way to “start-up” doing MP with Kingdom Come: Delieverance. An Act IV which represents a large ending battle where players can log in with the character that they have developed over the last three acts with all other soldiers / combatants being NPC’s - with either coop variants with players on one side or for those who like PvP with variants where logging in on opposing sides is possible.
This act would then be completely seperate from the other three and, as it would only represent a single battle, not have any influence on the character developments. Results could either be ignored or registered according to players preferences as it represents a completely seperate Act.
The whole idea is just to jump-start MP in a minimal way once the first three acts turn out to be a financial success - if it turns out well then it could be developed further.
What do you think?
