Iratus hit just The Spot for me. You get to be the evil guy here, fine balance between thinking and RNG, a bit of equip management, move-based combat, de/buff removal abilities... Fairly complex set of variables, but still in manageable size. You don't need a spreadsheet to play, but if you want to be perfect, you'll benefit from one.
You choose your way through the dungeon. Between combats, there's a base you benefit from: your minions can spend the "combat time" healing or studying. Don't get too attached, though. Your minions will die, sometimes even from one-shot. It will hurt, mainly in later stages of the game, when you invested some quality materials into your mobs. There's an option to instantly level-up your new creations through brain usage, so you'll only have the expected amount of troubles.
The downs of Iratus are mostly of cosmetic nature: lengthy animations (intro, combat moves...), sometimes hectic UI (when more enemies move in a row, you don't get to inspect their buffs, e.g.) and ugh, unlockable mobs.
You'll only have "basic" mobs available from the beginning, and you must perform certain actions to unlock new - such as collecting resources, dealing certain types of damage etc. This kind of progression through content is in my eyes way too much mobile-microtransactions-y. But the limits are not extreme in any kind. If you'll want to unlock all, you totally* can (*: additional purchases may be needed), if you don't want, you'll enjoy the game with what you found on the way.
