But it lacks some space-rogue stuff.
1) Free galaxy exploration. Being constantly pushed forward is kinda restraining.

2) Being able to devote time to teching up. FTL discourages me with the fact that i'm unable to upgrade my ship to the necessary extent. I just never find enough guns, schematics, shops and scrap. And the game pace does not let me to float around collecting stuff! You just run through the galaxy picking up what's on your way, not being able even to deliberately travel to a shop to buy a certain upgrade. D'oh!
3) Starting as a lone warrior. Being an empire's last hope in the first place drains all romantics out of the infinity of space. I'd rather be on my own, polishing my clunker and getting ready to breaking out of my homeworld. Being able to choose which faction to align to is crucial and a reputations system would be great. What if i wanna make a career of a pirate, running away from galaxy military forces all over the galaxy and looting good guys?
4) Trade. Okay, most of economy-based space exploration games are tedious. Getting rid of all trade from FTL made FTL a candy. But a space exploration game that lets you neither stuffing your cargo bay nor purchasing new ships (and taking them by force!) is... not a true space exploration game?
If FTL team announces FTL 2 with this kind of improvements, i'd pay three times as much as i had paid for beta access.
