These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Total Annihilation
Crowning Music of Awesome (Composer: Jeremy Soule. The intro music and the battle themes especially)
Some tracks seem to channel Star Wars - not that it is bad!
Fan Nickname (Many, such as "Blue Laser of Death" for the most powerful beam weapon, and "Gator" for the Instigator light tank.)
Game Breaker (Peewee, Flash, Brawler, nukes, fan-made unit Karganeth, although the latter is justified by its insane requirements — you're looking at about an hour to build the big guy.)
Unless you send in a fleet of construction planes to speed up the process. Given enough of them, you can have him in ten minutes. Of course the resource drain will be huge, so your economy has to be able to support it.
Air transports can only carry one ground unit at a time, but that includes enemy units. If an air transport carrying another unit is destroyed, the unit goes with it. Zerg Rush the enemy base with a flight of air transports, order them to pick up the Commander, and then laugh as the enemy forces continue firing,destroying their own Commander. Or use the self destruct.
Good Bad Bugs (Notably, the long-range artillery can be made even longer-range by commanding it to force-fire directly in front of it, which confuses the AI into elevating the barrel and throwing shells in an arc across the map)
Some mods "fix" this by increasing the artillery's max range to take advantage of this angle adjustment.
