I think doing episodes is very smart

Apart from the apparently great new Sam & Max series with a new episode per 1-2 months, Penumbra is the only other game I know to really use the concept of episodes in an appropriate way. 8 hours of gameplay for each episode, or even a little less, aren't far from the standard of modern action games, 20€ are in fact pretty cheap for that, and 6 months wait between each episode are also totally alright. Just about perfect, I'd say
