Thoughts on expansions

[Coin-coin le Canapin]

More stuff (creatures, spells...) doesn't always improve the gameplay...
It only my opinion, but except some issues you can see while playing only 2 minutes a small portion of the game (camera, pathfinding...) and things that doesn't modify the gameplay (background descriptions...), I don't really see how to talk about things that could be added in the game without playing the entire game.
Of course, I'm not talking about those who played the russian full version.
