Talisman: Prologue was a pretty great adaptation of GamesWorkshop's rather popular board game, but many seemed to view it as incomplete. I mean it was purely a solo affair, so that sort of makes sense. However, now Nomad Games is getting ready to release Talisman: Digital Edition and appease those who were hoping for a more multiplayer-driven affair.
Talisman: Digital Edition will still let you play against AI if you'd rather keep things solo, but it also offers asynchronous play. In case you're wondering how that works with spell interrupts, it basically uses a combination of push notifications and a timing window for players who want to try and counter an opponent's casting. Nomad also has plans for continuous support by adding new cards every few weeks, making new expansions available every few months, and even offering a curated library of user-created content.
You should be able to find Talisman: Digital Edition on the App Store for the iPad at the end of April for $7.99.
