I can confirm that KoH is a vastly underappreciated strategy gem. It's sort of like Crusader Kings' little brother mixed with real-time combat. Highly recommended.
SOTS is also really, really good if you like 4X Space games.
A Game of Dwarves looks fun but I've not played it that much yet, surprisingly. Basically a "lite" Dungeon Keeper if you will, except instead of monsters you control the greatest race in all of fantasy.
Unfortunately the only game from that bundle that entices me at all is Leviathan Warships. Hopefully I will see some giveaways for it on Steamgifts:P
