YMMV / Earth 2150

• Awesome Music: The music has been specially composed for the game, giving each side its own specific type of music. Eurasian Dynasty has pompous, militaristic classic music fitting its blunt, crude aspect; Lunar Corp eerie, spacey sounds akin their space hippie-ness; United Civilised States hard rock fitting their industrialized nation. The Moon Project takes this already awesome music, and adds an overproduced futuristic feel to it. Then there's the three sides' promo clips, where the UCS clip is structured more like a music clip (with Nukes) than a propaganda clip. The sequel, Earth 2160, comes bundled with a soundtrack CD, and given the nice selection of atmospheric tunes, you can't really blame them.
• Demonic Spiders: Until you start fielding shields, any UCS unit with a Heavy Plasma Cannon.
  • LC Thunderer bombers with Air Sonic Cannons are a MAJOR pain to deal with until you get shields. Their shots don't do much damage, but they have a very fast rate of fire and a massive damage radius, allowing just a few of them to wipe out an entire unshielded army in seconds.
• Game-Breaker: The ED's STEALTH vehicle equipped with an ion cannon. With this and a repairer-equipped Taiga, you can capture every ground unit on the level with near-impunity. In Moon Project, do this on the level with the Grizzlies and you'll overwhelm anything you face.
• Goddamned Bats: Enemy minelayers if you're not playing as LC. Left on their own for long enough, they will proceed to fill the entire map with hundreds of invisible landmines, of which ONE can kill any unit that isn't late-game. The only way to detect them is to use a minelayer of your own, which in the campaigns you tend not to get until about half a dozen missions after the enemy does.
• Les Yay: Played for Laughs; during one Mission Briefing of the Neo Campaign in the original game (playing LC and deciding to join with the ED) Neo mentions that in the case of Fang's superior not going with his methods, he will release videos of her making out with the girl from the progress department. She is understandably very angry about that.
• Low-Tier Letdown: For a number of people in Earth 2150, the LC is this. Despite being the most technologically advanced in-story, the LC are pretty awful with some very important technologies, most glaringly the repairer. Because they don't have one, the LC cannot upgrade their vehicles nor can they capture enemy units (despite having weapons that can paralyze enemy vehicles). Furthermore, their base artillery is the worst of the 3 factions and their anti-aircraft weapon is just awful. They also don't have an effective bomber with their equivalent being an aircraft armed with sonic cannons that doesn't do enough damage to pose much of a threat to enemies. Finally their superweapon is only effective on certain terrain otherwise it just creates weather effects that can hinder you as well as the enemy, and further even when it can do damage their superweapon doesn't match the firepower of those of the other factions.
• Nightmare Fuel:
  • During the timeframe of 2140, the ED performs Unwilling Roboticization on their own citizenry to reduce their ration requirements by way of turning them into cyborgs. They also practice Social Darwinism to such an extreme that laziness merits summary execution, which is their primary beef with the UCS due to the latter's heavy use of automation removing the citizenry's need to perform physical labor.
  • According to Fang, the UCS is not much better, with at least some of their vehicles running on a Brain in a Jar Wetware CPU.
  • The whole reason for the second half of Lost Souls' story. Not only did the leadership of all three factions leave behind most of their own population to die on a doomed Earth, they explicitly conspired with each other to actively prevent those left behind from finding another way off the planet in order to avert a Genocide Backfire.
• Sequel Difficulty Spike: Lost Souls is outright Nintendo Hard compared to its predecessors, with nearly every mission pitting the player against extremely fortified AI bases that not only attack continuously and relentlessly, but actually receive endlessly respawning high-end units as free reinforcements every few minutes.
• Sequel Displacement: Few people have heard of Earth 2140, which started the series, and was a fairly decent game in its own right, if not as spectacular or out of the ordinary as its sequels.
• That One Level: All of the first five or so ED missions tend to be unreasonably hard by virtue of the enemy sending highly-upgraded units at you just minutes into the missions. The worst is the semi-hidden Alaska mission where the player has to find a Soviet underground base (not very difficult), then has to mine 50,000 credits (doable) while being attacked by three UCS enemies spamming missile bots before the player is even allowed to construct anything (stupid).
• Too Bleak, Stopped Caring: No matter which side of which or version of game you play, Earth 2150 ends with Earth being destroyed, and billions perish. At best your action allow several tens of thousand to escape Earth.
