FTL is one of the finest roguelikes in gaming history, complete with a unique art style and captivating soundtrack. You start out with the most basic equipment, but you'll bulk up your ship from a massive selection of weapons, augments, drones, upgrades, systems/subsystems, and crew. It requires a bit of micromanagement and planning, but the element of roguelike luck keeps you on your toes so you never become too attached to one particular strategy.

"Missiles seem to be working well for me, but what if I run out?"
"Do I spend scrap on upgrading my blast doors, or risk being boarded by the Mantis or Rock?"
And above all,
"How much do I like burning things?"

With bombs, missiles, laser shots, laser beams, and flak weapons (which may cause hull, system, crew, breach, stun, ion, or fire damage while faring differently against shields, improved engines, cloaking, and defense drones), no full playthrough will ever be remotely the same, and you'll never want it to be.
