Greetings,
A game I think worth trying out on Zorin with Steam is "Legend of Keepers". You a mercenary for the bad guys who put up a lair which you have to defend from the heroes. You can hire new monsters or buy traps to ensure that the heroes don't get the hands on the treasures. Everything is upgradable if you have the money for it. Monsters, traps, spells, abilities can be upgraded.
Here's a video I made on Zorin OS. A dwarf boss and his party is trying to get the treasures from my human-hating Enchantress. Enjoy!
