I will compare the games between the prequel
Master of Orion and his sequel
Master of Orion II.
The
MOO has its characters in more cartoon style and more cute while the
MOOII has the more digitized style. An example would be the nice robot from GNN. In
MOO, the robot has a very cute appearance; Already in
MOOII, it has a more cool and distant appearance.
I do not remember if
MOO has its
champions or
heroes. Already in
MOOII, you need to select and reject if necessary, the best heroes or those that best fit your needs.
Not to mention that
MOOII background musics are great. Composer Laura really did a great job. I really enjoyed the BGM of the Galactic Map (except 1) and the Space Battle BGM.
In
MOOII you have the fearsome and bellicose
Antarians. If you have a technology that allows you to invade and conquer enemy ships, it would be very interesting to use it to invade
Antarians ships (if you do not use cheat codes) to obtain technologies available to the
Orions and
Antarians. But be careful, for
Antarians can self-destruct their ships if they are captured.
I conquered several
Antarians ships including invading the planet
Antares. I conquered the Space Base and all the
Antarians ships, but I could not get them into my galaxy. If you retire, the
Antarians ships and base will remain in the space of
Antares.
One thing that confused me is that if the Galactic Council appoints you as “Master of Orion” and you refuse the title, everyone declares war on you!
One sadistic thing I used to do to my opponents was to edit their Home Worlds: tiny-sized Planet; Planet of toxic radiation environment; Planet of mineral resources very poor; Only 01 Planet in the Solar System while the others are Asteroids.
EDIT:
I forgot to mention that I have two OST versions of the
MOO2 game, one that I got on the site and the other through
GOG.com.
I also forgot to mention the
Stellar Converter. I avoided using this powerful weapon so as not to destroy the planets. I pretty much forgot (or cannot remember) the technologies, but I had the technology of total invisibility.
