Personally, I get overwhelmed trying to make my characters "good guys" which often seems to require playing with low level characters (usually half) which end up dying very quickly after a few levels.
That's why you need to soften the other group up for the easy kills. It's easy to do and create a very holy army.
I've played the bad guy, killing rampage and then I never get to class upgrades I want.
Usually ALI is the culprit initially (Wizards to Mages can be a pain in the ass), but later, it extends to CHA due to high level groups beating the living crap out of low level groups. It's a delicate balance to rotate and deploy units and create what you want.
Here's some simple hints:
CHA is gained when lower level units kill higher level units.
CHA is lost when higher level units kill units 2 levels under the attacker (CHA is also lowered when you run away).
ALI is readjusted depending on the attacker's current ALI vs the target's current ALI.
If an evil unit (usually <= 35 ALI) kills another unit of the same level, the attacker tends to lose ALI .
If a holy unit (usually >= 65 ALI) kills another unit of the same level, the attacker tends to gain ALI.
If the target unit is considered holy normally (clerics, angels, etc.), the attacker tends to lose ALI.
If the target unit is considered evil normally (imps, wizards, etc.), the attacker tends to gain ALI.
If the target unit has a lower level than the attacker, the attacker tends to lose ALI.
If the target unit has a greater level than the attacker, the attacker tends to gain ALI.
A special exception is when both units are considered neutral (usually around 50 ALI) and have the same level... the default behavior is that the attacker loses ALI on the kill.
I find the game pretty frustrating. The graphics are wonderful which is a huge lure for me (Wonderful for sprites, I mean. They're not mind blowing.)
Generally, I love the idea of a tactical field, character formation placements and all that, but I HATE the real time board where they all move on.
The real time board is the fun part. You need to decide what movement rate you want to be running on...
I've heard of a Ogre Battle 2 that was ported/translated to the PS and I think there might be a Japanese only SNES version of it at well.
(I know this because I ripped the weapon sprites for personal use. He he)
I'm still waiting for the Tactics Ogre translation... there's like 3 revisions of the game for the SNES.
We have EVEN MORE themes now, but some old ones are gone...
