The graphic looks great.
But when introducing such a unit ingame a few points have to be clarified / thought about.
1. AI
If this unit is useful only in
very special cases we must prevent that AI is building / using this unit too much instead of the more generally usefuly Artillery.
Otherwise we will weaken AI.
AI is not wise enough to really handle "
very special purpose units" and thus it should not build / buy too many of them.
I agree. It is a very huge siege cannon, therefore we should limit the unit ingame.
2. Balancing
If this unit is generally very strong, then we must make it rare.
Otherwise we will destroy balancing when fighting Natives or Kings.
I agree, same as above.
3. UnitArtStyles / Atmosphere
If this should become a "Special Unit" (given by a DLL-Diplomacy Event) like "Hessian Mercenary" it would totally be ok for me to have only one graphic for all Europeans.
That graphic should show "neutral" uniforms then.
If this should become a "generally available Unit" (available through building / buying) then I would really prefer to have UnitArtStyles.
That would be no problem. I can make UnitArtStyles.
4. Usefulness / Differentiation
I don't like to bring units to the game only to have more great graphics.
Somehow units must be useful / interesting to the player.
I agree. As stated in my post, the unit should have it's own characteristics (siege cannon).
-------
Summary:
All of these points do not prevent to introduce that unit.
But they must be thought about / answered.
If this unit should either be very strong or very special purpose, I would suggest to bring them into the game with another (rare)
DLL-Diplo-Event.
(Thus we will prevent to unbalance the game or cause problems to AI. Also, we won't need UnitArtStyles for all Europeans.)
But what could such a DLL-Diplo-Event be about ?
(It should be a bit atmomspheric and not only "Do you want to buy this unit ?".)
