What is Solium Infernum?

This turn-based strategy game puts you in control of an Archfiend competing to rule Hell after Satan disappears.

Multiplayer matches can be played in one session or asynchronously.

+you enjoy planning several turns ahead of your rivals
+you want asynchronous multiplayer matches built around negotiation
+you like complex board-game strategy in a dark fantasy setting

Not for you if...

−you want brisk turns with plenty of actions
−you prefer straightforward warfare to political maneuvering

Some criticize the single-player AI or report bugs that prevent turns from being submitted.
