Suggest me a game.

fragile allegiance ps. you made 3 of these.

Batman Arkham Origins.

Alice: Madness Returns

One does not simply get bored of FTL with only 6 hours into it

Dark Souls, Borderlands 2

Bad Rats

I could suggest you something, but looking at the games you own... you don't really seem like someone to spend any money on it. Rendering my suggestions obsolete.

Transformice.

Dwarf Fortress

You just cannot get bored of that game.

Kill goblins will an exploding cart loaded with swords ? check.
Use their bones to make arrows to kill more goblins or make a throne ? check.
Flood the world with magma ? check
Cast elves into ice and use them as decoration ? chech
Release an ancient monster from times forgotten that will eat everybody, the survivors getting mad and killing each other ? check
try to figure out which one of your dwarves is a were ( wolf, cat, bunny, dunno, something ) ? check
having a dwarf loose his legs, eyes, arms, and win a fight by tearing apart the unicorns throat with his teeth ? check

Have fun.
