I've had a couple of 600pts. Path to Glory games (vs Soulblight) and a pitched battle at 1500pts (vs Lumineth).
The game is fun.
600pts. is fine to learn the basics, but the impact of every action is far greater. There's not a lot going on, so no hard choices on where to spend the CPs, losing a unit is a huge loss,...
Pitched Battles are nice. The secondary ways to earn VPs every turn are cool.
I managed to go first every round, but lost my general Turn 1 to lots of shooting, so was starving for CP the entire game.
I want to play more... (but if it isn't against Lumineth, better)
