Hello everybody.
As I know, many of you on this forum know everything about classic games. So I would like to ask you some help with two questions of quiz:

1. This Studio created games about 3 princes an 2 kings.
2. This studio was so good at working with video and at video processing, that these developers created a special and popular tool (or some software) for such tasks.

About first: I don't know how many games are about this (maybe two or maybe five). About second: this software was (or is) popular and it looks like maybe Pinnacle or something, I don't know. It just let you work with video, that's all I know.

Help please :/
Sorry, not about 2 kings, but about 2 emperors.
I'm not able to edit previous post on ipad :/

Dont know yet about 1 but 2: RAD Game Tools - http://www.radgametools.com/aboutrad.htm ?

Not 100% sure,but may be by 1 they mean Sierra?

RAD Tools maybe, yes, I agree.
And what about Sierra? Which games were about 3 princes and 2 emperors?

Emperors? Or Kings? :D Also I think Sierra made much more games about kings/princes than 5 total...

2 emperors and 3 princes :) that's correct
Maybe same princes or emperors were in different games?

If emperors then Impressions Games made games about Ceasar, Pharaon and Cleopatra, but princes... hmm...

According to mobygames here is list of games from Holistic Design, Inc.:
* Battles of Destiny
* Emperor of the Fading Suns
* Final Liberation: Warhammer Epic 40,000
* Hammer of the Gods
* Machiavelli the Prince
* Mall Tycoon
* Merchant Prince
* Merchant Prince II

One emperor is missing? :D

Heh, great, thanks :D I'll try to find one more emperor...

Hmm, unfortunately I can't find one more emperor... but looks like it's the only one possiable answer.

Look into Prince of Persia. Between the old games, the xbox titles and the recent new ones there might be one studio that did 3 of them.

That was my first idea also - already checked and I could not find any resemblances.
