if it was free, which indie gala game would you take?

so they have like 80 deals going on right now, i am looking for opinions on what game to get, but i dont want price to be a factor in the game selecting choice.

so picture it as just which game is absolutely good and worth it?

i already have all tropico games so not that one lol

EDIT: i agree with what your all saying, omerta, DARK, or demonicon are a couple that im highly considering, but some ppl told me just cuz they are high priced games doesnt mean they are good
