Just an idea of mine - the Dom3 Q&A thread

[ceremony]

Q1. Sure. The idea was to get your scout far enough across the map to reveal the AI before the tutorial ended. If you want to start building scouts early, feel free. The indies aren't going to change, though, and the AI is far enough away that you shouldn't have anyone encroaching on nearby provinces until well after the tutorial ends.

Q2. Have you adjusted the screen resolution in the Options menu? If you can go to 1600x1200 the sprites will be much sharper.

Q3. Undead priests can cast Unholy Protection/Protection of the Sepulchre, which gives undead +4 magic resistance, which helps a lot with the MR roll against Banishment. Spamming Banishment is a basic anti-undead tactic but has many counters. When you get the full game you'll be able to explore the various magic combinations. There are lots of ways to play undead (and lots of ways to play against undead).
