0 A.D. vs They Are Billions
0 A.D.
0 A.D. is a really unique game not because it is possibly one of the most well-made, open-source, historical real-time strategy games we've ever seen; the game started off as a mod for Age of Empires 2: The Age of Kings but ended up being a standalone game with its own game engine and everything. This is a pretty huge feat and puts 0 A.D. on the same level as other successful mod-turned games like Garry's Mod. However, the game may lose out a bit when it comes to popularity mainly because it's not available on Steam, which happens to be the current largest PC gaming platform, and partly because there isn't a lot of promoting from established gaming media, or marketing, even.That said, the game is incredibly impressive for an under-development and completely free game. You can play as a number of civilizations that has their own graphics and models to set them apart. There are also citizen-soldiers who like in real-life, can switch between gatheirng resources like a civilian and fighting as a soldier depending on need. Unlike certain RTS games that allow you to unlock every branch of the tech tree, this game offers technological tradeoffs between two equally important tech, forcing you to really consider your choices and pick one that fits your play style.
0 A.D. also tries to be as historically accurate as possible, conforming its 3D models and maps to actual historical depictions of the people and land back in the day. The effort into making game realistic is astounding, but of course, the devs have mentioned that if they had to choose between having a feature that's historically accurate or playable, they will definitely choose playable every time... naturally, since this is still mainly a game and all.
So, if you're interested, know that you can get the game for free on their site.
They Are Billions
They Are Billions is a hardcore, steampunk-themed empire-building/ real-time strategy game that is set in a dark and gloomy post-apocalyptic world (Not Earth). The game plays out like an actual RTS whereby you need to not only develop your castle into a sprawling empire, but also manage your empire's resources and defenses, and making sure that none of the billions of zombies out there are able to infiltrate your defenses... or things can easily escalate from having a single zombie to deal with to an entire horde.This indie game made waves in the gaming industry mainly because of its unique zombie system. As you all "The Walking Dead" fans should know, whenever a zombie attacks and kills a human, the plague that's around will reanimate the fallen corpse and turn it into a new zombie. This system is implemented in this game, making even a single zombie that had made it past your defenses a very costly mistake. That's not taking into account the periodic zombie invasions which usually consist of a massive swarm of zombies, some of which are tougher to kill than most, that sub-par defenses won't be able to handle.
They Are Billions is definitely not the sort of strategy game to play if you simply don't have the time or the patience to figure out the best strategy to protect your population from the many infected out there. However, if you're the sort who is always up for a challenge, you might find this game a rare delicious treat!
