Unfortunately; Fortunately

Unfortunately, the ship is called 'Titanic 2' ^^

Fortunately, it doesn't meet the same fate as 'Titanic 1', and you arrive there safely.

Unfortunately, someone miscalculated how much oxygen the ship needed to get there, so nearly half the people on board die.

Fortunately, the aliens on the planet hold the power to revive them.

Unfortunately, the aliens take advantage of our vulnerability and enslave us by threat of certain neglected death.

Fortunately, you start a rebellion!

Unfortunately, the aliens find that the rebellion is pretty darn feeble and quash it in no time.

Fortunately, a magic tree appears and revitalizes the spirit of the rebellion.

Unfortunately, the aliens chop it down and quash the rebellion as one would quash a bug underfoot.

Fortunately, there are civilizations outside this planet that aren't being oppressed, so one could assume that there is hope. And where there is hope, there is...well, hope. Which isn't really much, but it's fortunate!

Unfortunately, it's not enough to overthrow the alien oppressors.

Fortunatley, the new weapons you get are ^^

Unfortunately then the aliens stell the new weapons and use them on you.

Fortunately, earth gives more weapons and backup to the planet when they receive an anonymous distress call.

Unfortunately, that distress call was made by the aliens and they get all the weapons and back-up ^^
