FTL is a very fun game combining RTS elements with a roguelike permadeath and learning curve. The game is very difficult and incredibly punishing. The tiniest mistake usually means the entire ship gets blown up in a chain reaction of system failures, crew deaths, etc. Combat is difficult to master and involves timing and sequencing more than anything else. The ability to pause the game at any point to redirect crew and system power as soon as you unpause reduces from the real time strategy aspect of the game, but it's a necessary evil as there are simple too many things to micromanage and loading times on weapons can sometimes outpace your orders otherwise.
* Very difficult
* Highly replayable
* Lots of strategy in managing "scrap" for upgrades, new crew, new weapons, etc
* Minimal graphics, but everything is smooth and layed out well
* Great sound effects and pretty good music
* Lots of unlockable ships with different playstyles due to different layouts and starting crew / systems / weapons
* Different strategies are inherently less viable, and you're often funnelled into the typical "upgrade shields, upgrade engines, get boarding crew" strategy if you want to make it very far
* Random events are a bit less random than the game lets on, and to do well you pretty much have to just look up what the different outcomes are and their likelihoods. A new player would never just know not to try to fight the spiders. You have to either lose a crew member like 4 or 5 times to it, or just read a guide that tells you not to try that one because it's only successful like 15% of the time. That's just one example among many.
* Quite a bit of the game is just waiting. Once a battle finishes, you're ready to jump on to the next one. Except you've got to put out all the fires, wait for the oxygen to slowly come back, wait for your crew to slowly heal, slowly repair every damaged station, send your crew to slowly walk back to their default positions, and then finally NOW you can move on. This becomes very noticable and makes the game pretty damn boring at times.
* The game overall is just a bit too cryptic about some ♥♥♥♥. Most things go unsaid, and if you want to know why something happened the way it did, you just have to look up the guide for it. Seems kind of unnecessary for some things.
Overall, 8/10, fun and challenging game with only minor complaints after dozens of hours of play.
