[Lvl+1 GA] Guess and board the train (Hints added/Ends 06/18 12:30 am CEST)

Hi! I have another train for you. This time a little puzzle - guessing games from the screenshots. Don't worry - it's not nearly as hard as games from "Guess the Game" thread.
And I don't give away any game from screenshots, the train is much cheaper, sorry. :)
The cargo is :
Shoppe Keep
Brigador:Up-Armored Edition
WASTED
Volgarr the Viking
Small Radios Big Televisions
Gems of War - Demon Hunter Bundle
Californium
! That Bastard Is Trying To Steal Our Gold !
Desert Law
123 slaughter me street
The guard of dungeon
Redirection
Molemen must die!
Brute
Bloodbath Kavkaz
Steel Invaders
Stigmat
Bye-bye Wacky Planet!

Enter

EDIT. Added hints for those turned to be the most difficult for you.
